A WordPress upgrade may cause your website to stop loading due to a variety of reasons, such as incompatible plugins, theme incompatibility, memory limit issues, or a broken update. Here are some steps you can take to troubleshoot this issue:
1. Clear Cache and Cookies:
Your browser caches website data to speed up load times. However, this data can sometimes conflict with a recently updated site. Try clearing your browser’s cache and cookies and reloading the page.
2. Enable Debugging:
WordPress includes a debugging feature that can help identify any PHP errors causing your site to malfunction. To enable this feature, edit your wp-config.php file and change define('WP_DEBUG', false); to define('WP_DEBUG', true);. This should display any errors when you attempt to load your site.
3. Deactivate Plugins:
Incompatibility between the new WordPress version and your existing plugins is a common cause of website failure after updates. If you have access to your WordPress admin area, try deactivating all plugins and then reactivate them one by one until you find the one causing the issue.
If you don’t have access to the admin area, you can deactivate plugins via FTP. Connect to your site using an FTP client, navigate to /wp-content/, and rename the ‘plugins’ folder to something like ‘plugins_old’. This deactivates all your plugins. If your site starts working, it confirms that a plugin is causing the issue.
4. Switch to a Default Theme:
In some cases, your current WordPress theme may be incompatible with the updated version of WordPress. If you have access to your WordPress admin area, try switching to a default theme like Twenty Twenty. If you can’t access the admin area, you can switch themes via FTP. Just navigate to /wp-content/themes/ and rename your current theme’s folder.
5. Increase Memory Limit:
WordPress may require more memory than your server is currently configured to provide, especially after an update. You can increase the PHP memory limit in WordPress by editing your wp-config.php file. Add this line to the file: define('WP_MEMORY_LIMIT', '256M');.
6. Restore a Backup:
If you have a recent backup of your site, you might consider restoring it. This could resolve the issue if it’s due to a broken update or a conflict that’s difficult to identify.
7. Contact Your Host:
If none of these solutions work, there might be a server issue, or the update may not have completed correctly. Contact your hosting provider for further assistance.
Remember to always keep a backup of your site before performing any major changes like an upgrade. This can help you to easily restore your site in case anything goes wrong.
