Here’s how to fix WP-Admin AJAX Failures in WordPress:
Fix .htaccess Issues:
- Backup your current .htaccess file
- Create a new .htaccess with these basic WordPress rules:
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
Check WordPress Address (URL) Settings:
- Go to Settings → General
- Ensure both “WordPress Address (URL)” and “Site Address (URL)” are correct
- Make sure they use the same protocol (both http or both https)
Increase PHP Limits: Add to wp-config.php:
define(‘WP_MEMORY_LIMIT’, ‘256M’);
set_time_limit(300);
Disable mod_security (if possible): Add to .htaccess:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
Check AJAX URL Definition: Add to wp-config.php:
define(‘ADMIN_COOKIE_PATH’, ‘/’);
define(‘COOKIE_DOMAIN’, ”);
define(‘COOKIEPATH’, ”);
define(‘SITECOOKIEPATH’, ”);
Debugging AJAX: Add to wp-config.php:
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
If these steps don’t resolve the issue, you might need to:
- Clear browser cache and cookies
- Try a different browser to rule out browser-specific issues
- Temporarily disable all other plugins to check for conflicts
- Check server error logs for specific error messages
Remember to backup your site before making any of these changes, especially when modifying core WordPress files.
