50+ Common WordPress Errors and How to Fix Them (Troubleshooting Guide)
WordPress is a powerful and popular content management system, but like any software, it can encounter errors and issues. In this troubleshooting guide, we’ll explore some common WordPress errors and provide solutions to help you resolve them.
- “White Screen of Death” (WSOD):
- Solution: Disable plugins by accessing your website via FTP or the file manager in your hosting control panel. Rename the “plugins” folder to something like “plugins_deactivated” and create a new empty “plugins” folder. This will deactivate all plugins, allowing you to identify the problematic one.
- 404 Page Not Found Error:
- Solution: Refresh your permalinks by navigating to Settings > Permalinks and clicking “Save Changes” to regenerate the rewrite rules. If the issue persists, check your .htaccess file for any incorrect configurations.
- Internal Server Error:
- Solution: Increase the PHP memory limit by adding the following line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '256M');
. If the issue persists, disable all plugins and switch to a default WordPress theme to identify the cause.
- Database Connection Error:
- Solution: Verify your database credentials in the wp-config.php file. Check the hostname, username, password, and database name. Contact your hosting provider if you’re unsure about the correct details.
- “Briefly unavailable for scheduled maintenance” Message:
- Solution: This message appears during automatic updates. Delete the .maintenance file from your website’s root directory using FTP or the file manager.
- Syntax Error or Parse Error:
- Solution: Review the code you recently added or modified. Check for missing or misplaced brackets, parentheses, or semicolons. Revert the changes if necessary.
- Memory Exhausted Error:
- Solution: Increase the PHP memory limit by adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '256M');
. If the issue persists, contact your hosting provider to raise the limit.
- Login Page Refresh/Redirect Loop:
- Solution: Clear your browser cookies and cache. Disable any security plugins temporarily to check if they’re causing the issue. Ensure your WordPress Address and Site Address URLs in Settings > General are correct.
- Missing Stylesheet Error:
- Solution: This error occurs when uploading a wrong file. Ensure you’re uploading the actual theme’s .zip file, not the entire download package.
- “Error Establishing a Database Connection”:
- Solution: Verify your database credentials in the wp-config.php file. Check if your database server is running. Contact your hosting provider if you need assistance with database connectivity.
- Broken or Missing Images:
- Solution: Check the image file paths in your content and ensure they’re correct. Regenerate thumbnails using the “Regenerate Thumbnails” plugin if necessary.
- HTTP Error When Uploading Images:
- Solution: Increase the PHP memory limit by adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '256M');
. Additionally, check if the upload directory has proper write permissions (typically 755 or 775).
- “Are You Sure You Want to Do This?” Error:
- Solution: This error often occurs due to a security token mismatch. Clear your browser cookies and cache. If the issue persists, check for conflicting plugins or themes.
- Too Many Redirects Error:
- Solution: Clear your browser cookies and cache. Check your site URL settings in Settings > General and ensure they match the actual site URL.
- “Allowed Memory Size Exhausted” Error:
- Solution: Increase the PHP memory limit by adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '256M');
. If the issue persists, contact your hosting provider to raise the limit.
Remember to always create a backup of your WordPress site before making any changes, especially when troubleshooting. If you’re unsure about handling a specific error, consult with a professional or reach out to the WordPress support community for assistance.
