A crashed WordPress site can be a nightmare, especially if your business relies on it for sales and customer engagement. Whether your site is showing the dreaded “White Screen of Death,” a critical error, or simply won’t load, quick troubleshooting is crucial. This guide walks you through the most common causes of WordPress site crashes and how to fix them effectively.
Step 1: Identify the Cause of the Crash
Before attempting any fixes, determine what caused the crash. Here are some common culprits:
- Plugin or theme conflicts
- WordPress core update issues
- PHP errors or server-related issues
- Database corruption
- Malware or hacking attempts
- Exceeded resource limits on hosting
Step 2: Enable Debugging Mode
WordPress has a built-in debugging feature that can help you pinpoint issues. To enable debugging:
- Access your site’s files via FTP or cPanel.
- Open the wp-config.php file.
- Add the following code before the line that says “That’s all, stop editing!”:
- define(‘WP_DEBUG’, true);
- define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, false);
- Save the file and check the debug.log file inside the wp-content folder for errors.
Step 3: Deactivate Plugins & Themes
A faulty plugin or theme is often the cause of a site crash.
- Disable Plugins:
- Access your site via FTP or cPanel.
- Navigate to wp-content/plugins and rename the plugins folder (e.g., plugins_old).
- If the site loads, rename the folder back and deactivate plugins one by one to identify the culprit.
- Switch to a Default Theme:
- Go to wp-content/themes and rename your active theme folder.
- This forces WordPress to switch to a default theme (e.g., Twenty Twenty-Three).
Step 4: Restore a Recent Backup
If troubleshooting doesn’t resolve the issue, restoring a previous backup may be the fastest solution.
- Use backup plugins like UpdraftPlus, BackupBuddy, or Jetpack.
- If you have a hosting backup, restore your site via your hosting control panel.
Step 5: Check for PHP Errors & Server Issues
- Check your hosting error logs for PHP-related issues.
- Ensure you’re using a compatible PHP version (check under Hosting Settings or ask your host for assistance).
- If you’ve recently updated WordPress, ensure your plugins and theme are compatible with the latest version.
Step 6: Scan for Malware or Security Breaches
If your site was hacked, you’ll need to clean malicious files and strengthen security.
- Use security plugins like Wordfence, Sucuri, or MalCare to scan for malware.
- Reset all passwords and update security settings.
- Contact your hosting provider for security assistance if needed.
Step 7: Increase PHP Memory Limit
If your site crashes due to resource exhaustion, increase the PHP memory limit:
- Edit the wp-config.php file.
- Add this line:
define(‘WP_MEMORY_LIMIT’, ‘256M’);
- Save the file and refresh your site.
Step 8: Contact Your Hosting Provider
If you’ve exhausted all troubleshooting steps and your site is still down, contact your web host. They can check server logs, restore backups, and identify deeper issues.
Prevent Future WordPress Crashes
- Regularly update WordPress, plugins, and themes.
- Use a reliable backup system.
- Implement WordPress speed optimization to prevent resource exhaustion.
- Strengthen security with firewalls and malware scans.
- Choose quality hosting with adequate resources and support.
