Seeing a Critical Error Warning when trying to access your WordPress admin can feel overwhelming, but the good news is that it’s usually fixable. While you may be focused on troubleshooting this issue, it’s also a good time to review other site management tasks, such as learning how to add an author properly. By addressing both the error and your user roles, you ensure your website runs smoothly.
When you add an author in WordPress, you improve collaboration and give credit where it’s due, but errors like the Critical Error Warning can interrupt workflows. Knowing how to resolve this error quickly and continuing to add an author with the right permissions keeps your site secure, professional, and efficient. Taking these steps together saves time and reduces stress.
What causes a critical error warning in WordPress?
The critical error in WordPress is caused by:
- Plugin or Theme Conflicts: New plugin/theme installed or updated.
- PHP Errors: Outdated or incompatible PHP versions.
- Memory Limit Exhaustion: Out of allocated memory on your server.
- Corrupted Files: Core files or updates gone wrong.
Follow the steps to Fix Critical Error Warning
Step 1: Check Your Email for Error Details
When WordPress detects a critical error, it will send an email to the admin email with details. This email will include:
- A link to Recovery Mode.
- Information about the plugin, them, or file causing the error.
Check your inbox (and spam folder) for this email – it’s usually the quickest way to get back into your admin.
Step 2: Recovery Mode
If you got the Recovery Mode email, follow these steps:
- Click on the Recovery Mode link in the email.
- Log in to your WordPress admin area.
- Deactivate the problematic plugin or theme.
Pro Tip: If you’re unsure which plugin or theme caused the error, deactivate them individually and refresh the site after each deactivation to find the culprit.
Step 3: Access Your Site via File Manager or FTP
If you didn’t get the email, you can use your hosting’s File Manager or FTP client (like FileZilla) to access and fix the issue.
Here’s How:
- Log in to Your Hosting Account: Access the control panel (e.g., cPanel).
- Go to wp-content Folder: Find your plugins or themes folder.
- Rename Plugin/Theme Folder: Rename the suspected plugin or theme folder to deactivate it.
- For example, change the plugin name to disable the plugin.
- Reload Your Site: Check if the error resolves.
Step 4: Increase PHP Memory Limit
Low memory limits are a common cause of critical errors. Here’s how to increase the PHP memory limit:
- Open your wp-config.php file in your site’s root directory.
- Add the following line of code:
define( 'WP_MEMORY_LIMIT', '256M' );- Save the file and refresh your site.
Step 5: Update PHP Version
Make sure your hosting server is using the latest supported PHP version:
- Log in to your hosting control panel.
- Go to Tools → Site Health.
- Go to the Info tab and expand the Server category to see the website’s current PHP version.
- Select a newer PHP version (7.4 or above is recommended).
- Save and reload your site.
Step 6: Debug the Issue
Turn on WordPress debug mode to find the cause:
- Edit your WP-config.php file.
- Add or modify the following lines:
define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true );- Check the debug log in the wp-content/debug.log file for the error details.
Note: Disable debug on live sites to avoid exposing sensitive info.
Step 7: Restore a Backup
- If you’ve tried everything and the error persists, restoring your site to a previous backup is the way to go. Use your hosting backup tool or a plugin like UpdraftPlus or Solid Security to roll back to a working state.
Step 8: Contact Your Hosting Provider
- If all else fails, your hosting provider’s support team can usually help you troubleshoot and fix the issue. Provide them with any error details you have.
Preventing Future Critical Errors
- Update Plugins, Themes, and WordPress Core: Keep up to date.
- Choose quality plugins and themes: Only use trusted, updated extensions.
- Use a Staging Site: Test updates on a staging site before applying to a live site.
- Monitor Your Site: Use tools like Jetpack or Wordfence to catch issues early.
