Steps to Fix Your Crashed Site
Follow these steps to troubleshoot and fix your site.
1. Check Php Version Compatibility
First, check if your themes and plugins are compatible with PHP 8.1. Visit the plugin and theme pages. Look for compatibility information.
2. Enable Debugging Mode
WordPress has a debugging mode. It helps you find errors. To enable it, follow these steps:
- Access your site’s wp-config.php file.
- Find the line that says
define('WP_DEBUG', false); - Change it to
define('WP_DEBUG', true); - Save the file and refresh your site.
You will now see error messages. These messages help you find the problem.
3. Deactivate All Plugins
Sometimes, a plugin is the problem. Deactivate all plugins to see if the site works. Follow these steps:
- Access your site’s files via FTP or your hosting control panel.
- Navigate to the wp-content folder.
- Rename the plugins folder to plugins-deactivated.
- Check your site to see if it loads.
If your site loads, one of your plugins is incompatible. Rename the folder back to plugins. Then, activate each plugin one by one. This helps you find the problematic plugin.
4. Switch To A Default Theme
Your theme could also be the issue. Switch to a default WordPress theme. Follow these steps:
- Access your site’s files via FTP or your hosting control panel.
- Navigate to the wp-content/themes folder.
- Rename your current theme’s folder to something like theme-old.
- WordPress will now use a default theme like Twenty Twenty-One.
- Check your site to see if it loads.
If your site loads, your theme is incompatible with PHP 8.1. Contact the theme developer for support.
5. Restore From Backup
If the above steps don’t work, restore your site from a backup. Most hosting providers offer backup services. Follow these steps:
- Log in to your hosting control panel.
- Find the backup section.
- Choose a backup from before the PHP update.
- Restore your site.
After restoring, your site should work again. Make sure to check plugin and theme compatibility before updating PHP again.
