Running a WordPress website in the UAE is genuinely easy right up until the moment something breaks. Then it feels like staring at a car engine with the hood up, knowing nothing. The good news: almost every WordPress error you will ever encounter has been hit a thousand times before, diagnosed, and solved. This guide covers the 20 most common WordPress errors UAE site owners actually face, with the exact error messages you will see, what causes them, step-by-step fixes, and how to prevent each one from coming back. Bookmark this page, it will save you a panicked Friday evening at some point.
WP_DEBUG. Most errors are a single plugin or theme file away from being resolved. If you are on AEserver’s managed WordPress hosting in Dubai, our support team fixes most of these for you.
The single most important rule of WordPress troubleshooting: take a full backup before making any fix. Every step in this guide modifies files, databases, or both. A bad fix can turn a minor issue into a dead website.
How to back up quickly:
public_html (or your site’s web root) via FTP/SFTP, and export your database as a .sql file through phpMyAdmin.For a full backup strategy, see our WordPress backup guide, our website backup service for automated daily snapshots, or our Acronis backup service for enterprise-grade infrastructure backup in the UAE.
WordPress has a built-in debugging mode that turns silent failures into readable error messages. Enable it as your first troubleshooting step.
Connect via FTP or File Manager, open wp-config.php in your WordPress root, find the line that says /* That's all, stop editing! */, and right above it add (or modify):
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);
This logs errors to /wp-content/debug.log without showing them to visitors. After troubleshooting, set WP_DEBUG back to false on production. For more, see WordPress’s official debugging documentation.
WP_DEBUG_DISPLAY set to true on a live production site. Displaying raw PHP errors publicly can expose file paths, database structure, and server configuration to anyone visiting the page, including attackers.
What you see: A completely blank white page. No header, no content, no error message. The browser shows a blank tab titled with your URL.
Causes: PHP fatal error (usually from a plugin or theme), memory limit exhausted, broken theme file, incompatible PHP version, or corrupted WordPress core files.
Fix:
WP_DEBUG as above, reload the page, and check /wp-content/debug.log for the fatal error/wp-content/plugins/ (e.g., broken-plugin to broken-plugin.OFF) to disable it/wp-content/themes/ to force WordPress to fall back to a default themeplugins.OFF, log into WordPress, then rename it back and reactivate plugins one by onewp-config.php and /wp-content/ intactPrevention: Keep WordPress core, themes, and plugins updated. Use a staging environment to test updates before applying to production. AEserver’s managed WordPress auto-updates minor releases safely.
What you see: A single-line message: “There has been a critical error on this website. Please check your site admin email inbox for instructions.” This replaced the raw White Screen of Death in WordPress 5.2+.
Causes: Same as WSOD, a fatal PHP error in a plugin, theme, or custom code. WordPress now catches these and shows the message instead of blank page.
Fix:
WP_DEBUG, rename plugins folder)Prevention: Make sure your admin email is working. Set up email delivery via AEserver business email so WordPress recovery messages actually reach you.
What you see: “500 Internal Server Error”, or “The server encountered an internal error or misconfiguration”. Sometimes a generic cPanel or Nginx branded page.
Causes: Corrupt .htaccess file, PHP memory exhausted, faulty plugin, PHP version mismatch, or server-level configuration issue.
Fix:
.htaccess to .htaccess_old via FTP, then reload the site. If it works, log into WordPress > Settings > Permalinks > click Save (regenerates a fresh .htaccess)/wp-content/plugins/ folder), reloadwp-config.php:
define('WP_MEMORY_LIMIT', '256M');Prevention: Keep plugins updated. Run PHP 8.1 or 8.2 (what AEserver offers). Avoid editing .htaccess directly unless you know what you are doing.
What you see: A plain white page reading exactly “Error establishing a database connection”.
Causes: Wrong database credentials in wp-config.php, database server is down, database exceeded connection limit, or the database is corrupted.
Fix:
wp-config.php and verify: DB_NAME, DB_USER, DB_PASSWORD, DB_HOST (usually localhost on shared hosting)wp-config.php:
define('WP_ALLOW_REPAIR', true);
then visit yourdomain.ae/wp-admin/maint/repair.php and click “Repair Database”Prevention: Do not share database users across sites. Limit database connection count in your PHP settings. AEserver’s hosting monitors database health automatically.
What you see: “Parse error: syntax error, unexpected ‘…’ in /home/username/public_html/wp-content/themes/yourtheme/functions.php on line XX”. Always points to a specific file and line.
Causes: You (or someone) edited a PHP file and introduced a typo: missing semicolon, unmatched bracket, stray character. Often happens when pasting code snippets from tutorials.
Fix:
;, }, ), or mismatched quotesPrevention: Never edit PHP files in WordPress admin (Appearance > Theme File Editor, Plugins > Plugin File Editor). Always edit locally with an IDE that catches syntax errors before upload. Better still, add custom code via a child theme or a Code Snippets plugin.
What you see: “Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate XXXX bytes)”. The number is the current limit in bytes.
Causes: Your PHP memory limit is too low for WordPress + plugins + theme. Common with WooCommerce, Elementor, large image processing, or imports.
Fix:
wp-config.php (above /* That's all, stop editing! */):
define('WP_MEMORY_LIMIT', '256M');
define('WP_MAX_MEMORY_LIMIT', '512M');php.ini or .user.ini in the site root: memory_limit = 512Mmemory_limit to 512MPrevention: Run on hosting that offers at least 256M PHP memory by default. AEserver’s WordPress hosting provides generous memory limits. For memory-hungry sites (WooCommerce with many products, large membership sites), upgrade to Cloud VPS in Dubai.
What you see: “Fatal error: Maximum execution time of 30 seconds exceeded in /home/username/public_html/wp-content/…”
Causes: A PHP script took longer than the allowed time, usually during imports, backups, theme installation, plugin update, or database operations.
Fix:
wp-config.php: add
set_time_limit(300);(300 seconds)
.htaccess:
php_value max_execution_time 300
max_execution_time to 300Prevention: Avoid importing thousands of posts/products in one go. Use WP-CLI for heavy database work. Schedule heavy tasks during low-traffic hours.
What you see: Homepage works, but every other page (posts, categories, archives) returns 404. Usually appears suddenly after a migration, URL change, or .htaccess problem.
Causes: Broken .htaccess rewrite rules, mod_rewrite disabled on server, changed permalink structure without flushing rewrite rules.
Fix:
.htaccess).htaccess in your root folder, it should contain the default WordPress rewrite block. Replace with this default:# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
mod_rewrite is enabled, contact your host if unsure.htaccess, your host needs to set themPrevention: Do not manually edit .htaccess unless necessary. After migrations, always re-save permalinks as the first step.
What you see: “Briefly unavailable for scheduled maintenance. Check back in a minute.” and it never goes away.
Causes: A WordPress update (core, plugin, or theme) was interrupted, by a browser timeout, connection drop, or PHP error. WordPress creates a .maintenance file during updates and deletes it when done. If the update broke, the file stays.
Fix:
.maintenance (note the leading dot). File manager needs “Show Hidden Files” enabledPrevention: Do not close your browser during WordPress updates. Use a stable internet connection. Update plugins one at a time rather than bulk. AEserver managed WordPress handles this automatically with update retries.
What you see: When trying to update anything: “Another update is currently in progress.”
Causes: A previous update died mid-way and left a lock in the database. WordPress uses a transient (core_updater.lock) to prevent simultaneous updates.
Fix:
wp_options table (prefix may differ)option_name = core_updater.lockAlternative (via WP-CLI):
wp option delete core_updater.lock
Prevention: Do not interrupt updates. Keep a stable connection during admin work. Automatic updates on AEserver managed WordPress don’t trigger this issue.
What you see: “502 Bad Gateway” or a Cloudflare-branded error page.
Causes: The web server (Nginx or Apache) could not get a valid response from PHP-FPM or the backend. Usually PHP crashed, ran out of memory, or hit a timeout. Sometimes a CDN (Cloudflare) cannot reach your origin server.
Fix:
Prevention: Monitor your server resources. Upgrade from shared hosting to VPS if you consistently hit memory limits. Keep PHP and WordPress updated.
What you see: “504 Gateway Timeout”. Often occurs on slow, heavy pages (analytics dashboards, plugin update screens, large imports).
Causes: A long-running request took more time than the server allows before responding. PHP-FPM or upstream timeout exceeded.
Fix:
max_execution_time and web-server proxy_read_timeout/fastcgi_read_timeoutPrevention: Use a caching plugin. Avoid running multiple heavy tasks simultaneously. Upgrade to Cloud VPS or dedicated server if your site has grown beyond shared hosting.
What you see: “This page isn’t working, yourdomain.ae redirected you too many times. ERR_TOO_MANY_REDIRECTS”.
Causes: A conflict between HTTP/HTTPS rules in .htaccess, WordPress Settings, and your CDN/reverse proxy. A force-HTTPS plugin fighting a redirect at server level, or Cloudflare “Flexible” SSL fighting WordPress’s own HTTPS enforcement.
Fix:
https:// if you use SSL.htaccess for redirect rules, make sure there is only ONE redirect (HTTP to HTTPS), not multiple chained redirectswp-config.php for hardcoded WP_HOME or WP_SITEURL that conflicts with your actual URLPrevention: Configure SSL in one place, not three. On AEserver hosting with AutoSSL and Cloudflare, use Full SSL mode only.
What you see: You enter correct credentials at /wp-admin/, the page reloads, and you are back at the login screen. No error message.
Causes: Corrupted WordPress cookies, session problems, conflicting site URL vs database URL, or a misconfigured security plugin.
Fix:
wp-config.php, remove any hardcoded WP_SITEURL and WP_HOME lines temporarilywp_users table, find your user, edit user_pass, select MD5 function, enter new passwordfunctions.php for rogue code (common hacking target), look for unfamiliar PHP at the top of the filePrevention: Use a reputable security plugin (Wordfence, iThemes, Sucuri) but only one at a time. Keep your admin password strong. Enable 2FA for admin accounts.
What you see: Padlock icon shows a warning triangle. Browser console shows: “Mixed Content: The page at ‘https://yourdomain.ae/’ was loaded over HTTPS, but requested an insecure resource ‘http://…’.”
Causes: After migrating from HTTP to HTTPS, some images, scripts, or stylesheets are still linked with http://. Browsers block or warn on these.
Fix:
http://yourdomain.ae, Replace: https://yourdomain.aehttp:// URLsPrevention: Do HTTPS migration properly the first time. Update both Site URL fields. Use a search-and-replace tool, not find-and-replace in the database manually. See our SSL certificates guide for the full HTTPS setup.
What you see: You scheduled a post for a future date. The time passes, but the post stays with status “Missed Schedule” instead of publishing.
Causes: WordPress’s built-in “cron” (WP-Cron) only runs when a page is visited. On low-traffic sites or aggressively cached sites, the cron may not fire at the scheduled time.
Fix:
wp-config.php:
define('DISABLE_WP_CRON', true);
then set up a real cron in cPanel > Cron Jobs, running:
wget -q -O - https://yourdomain.ae/wp-cron.php >/dev/null 2>&1every 5-15 minutes
wp-cron.phpPrevention: Replace WP-Cron with real server cron on any production site. This fixes missed posts, missed backup schedules, and scheduled email digests simultaneously.
What you see: In the Media library, upload shows “HTTP error” or “The file could not be uploaded”. No further detail.
Causes: Many possibilities: server memory, mod_security rules, ImageMagick/GD library issue, PHP upload size limit, insufficient folder permissions, or a security plugin blocking the upload.
Fix:
upload_max_filesize and post_max_size to 64M or higher/wp-content/uploads/ and all subfolders should be 755 (folders) and 644 (files).htaccess (if mod_security is blocking):
<IfModule mod_security.c> SecFilterEngine Off SecFilterScanPOST Off </IfModule>
wp-config.php, try forcing a specific image library:
define('WP_IMAGE_EDITOR', 'WP_Image_Editor_GD');Prevention: Compress images before upload (TinyPNG, ShortPixel). Use WebP format. Use an image optimisation plugin (ShortPixel, Smush, Imagify) to handle oversized uploads automatically.
What you see: “WordPress has failed to upload due to an error, Unable to create directory wp-content/uploads/2025/01. Is its parent directory writable by the server?”
Causes: The uploads folder or its parent does not have write permission. Usually happens after a migration or restore where file ownership got lost.
Fix:
/wp-content/uploads/ and check permissionsroot or nobody. If wrong, contact your host to fix ownership/wp-content/uploads/2025/01, manually create that folder via FTPPrevention: When migrating WordPress, preserve file ownership by using a migration plugin (Duplicator, All-in-One WP Migration) rather than raw FTP copy.
What you see: Contact form submissions never reach your inbox. New user registrations, password resets, and order confirmations don’t arrive. No obvious error, just silence.
Causes: WordPress’s default wp_mail() uses PHP’s mail() function, which most modern hosts throttle or block entirely. Gmail, Outlook, and UAE corporate email providers mark these as spam because they fail SPF/DKIM/DMARC checks.
Fix:
Prevention: Never rely on PHP mail() for transactional email. Always use authenticated SMTP.
What you see: Any of these: unknown spam posts appear, new admin users you did not create, “Japanese SEO spam” keywords in Google search results, redirects to sketchy domains, browser blocks your site as “Deceptive”, Google Search Console warnings, customer complaints about weird behaviour.
Causes: Outdated WordPress core, plugin, or theme; compromised admin password; vulnerable plugin; malicious theme downloaded from a non-official source; weak hosting.
Fix (act fast):
wp-config.php with new DB password), cPanel, FTP, emailfunctions.php for injected code, look for eval(), base64_decode(), obfuscated strings/wp-content/uploads/ for .php files that should not be there (PHP should never live in uploads)Prevention: Keep WordPress core, plugins, themes updated (auto-update on AEserver managed). Use strong passwords + 2FA. Install a Web Application Firewall (Wordfence, Sucuri, or Cloudflare). Take regular off-site backups. Avoid nulled/pirated plugins and themes. See our full WordPress cyberattacks prevention guide.
Hitting even one of the 20 errors above is painful. The same five habits prevent roughly 80 percent of them:
DIY fixing WordPress errors is satisfying until you hit one that keeps biting after three different fixes. Call your hosting provider when:
AEserver’s UAE-based support team runs 24/7/365 with hotline hours 9 AM to 6 PM Mon to Sat. For most WordPress-specific issues, support responds within minutes on managed plans. English and Arabic support available.
WordPress powers roughly 43 percent of all websites globally, and a disproportionate share of UAE business sites. Errors are part of the territory. The difference between a five-minute fix and a five-day outage is preparation: backups, debug access, knowing where to look, and picking hosting that handles the boring maintenance for you.
For UAE site owners, the practical takeaway is this:
WP_DEBUG when things break, work through the fix, and prevent the next recurrenceEvery error above has been solved thousands of times. You are not the first person to hit it, and you will not be the last. When you are stuck, AEserver’s team has been running WordPress infrastructure in the UAE since 2008, reach out, we have probably seen your exact error yesterday.
