What Are WordPress Fatal Errors?
A WordPress fatal error happens when something goes seriously wrong on your site, stopping it from loading properly. Unlike other WordPress errors that might only affect part of your site, a fatal error can bring your entire website down, showing a blank screen or an error message instead of your content.
These errors usually occur when WordPress can’t run as expected. Common causes include conflicts between plugins or themes, issues with your site's memory limit, or even corrupted files. For example, if two plugins don’t work well together, they might cause the site to crash. Similarly, if your website is using too much memory, it could trigger an error.
Fatal errors are more serious than other WordPress errors like a missing image or broken link, as they prevent the site from functioning altogether. Understanding the cause of a WordPress fatal error is the first step in getting your site back online.
Common WordPress Fatal Errors Message:
When a WordPress fatal errors occurs, you’ll usually see an error message that gives you a clue about what went wrong. Here are some common ones:
1. Allowed Memory Size Exhausted:
This means that your site has run out of the memory allocated for it to function. WordPress needs a certain amount of memory to handle plugins, themes, and other processes. If it uses more than allowed, the site crashes and this error pops up. Go through our previous blog to learn fixing WordPress memory limit error.
2. Maximum Execution Time Exceeded:
This happens when a task on your site takes too long to complete. WordPress only allows scripts to run for a limited amount of time to avoid overloading the server. If something takes too long, like a big import or a slow plugin, you'll see this error. You can fix it by increasing the maximum execution time.
3. Error Establishing a Database Connection:
This one shows up when WordPress can’t connect to your database, where all your content is stored. It could be caused by incorrect login details, a corrupted database, or server issues.
Understanding these messages can help you know where to start when fixing a WordPress fatal error. Each one points to a specific issue, so you can take the right steps to resolve it.
Troubleshooting WordPress Fatal Errors:
When you encounter a WordPress fatal error, it can seem overwhelming, but there’s no need to panic. Here’s a simple step-by-step guide to help you troubleshoot and resolve the issue.
Step 1: Enable Debug Mode
The first thing you should do is enable WordPress debug mode. This feature provides more detailed error messages, helping you understand what’s causing the fatal error. To enable it, you’ll need to access your wp-config.php file in your WordPress root directory.
Here’s how to do it:
- Use an FTP client or your hosting provider’s file manager to access your WordPress files.
- Open the wp-config.php file.
- Find the line that says `define('WP_DEBUG', false);`.
- Change `false` to `true` and save the file.
Now, when you reload your site, you should see a more detailed error message that points you in the right direction.
Step 2: Check for Plugin or Theme Conflicts
One of the most common causes of a WordPress fatal errors is a conflict between plugins or between a plugin and your theme. If you’ve recently installed or updated a plugin or theme, that might be the culprit.
Here’s what you can do:
- Deactivate all plugins: Go to your WordPress dashboard, click on “Plugins,” and deactivate them all. If your site works after this, one of your plugins is causing the problem. To find out which one, reactivate them one by one until the error reappears.
- Switch to a default theme: If deactivating plugins doesn’t fix the issue, try switching to a default WordPress theme like Twenty Twenty-Three. If the error goes away, your theme is likely causing the problem.
If you're facing issues with conflicting themes, one effective solution is to consider using premium WordPress templates, like those offered by Buy WP Templates. Premium themes are typically developed with higher compatibility standards, reducing the chances of conflicts with plugins or core WordPress updates. These themes often come with dedicated support and regular updates, ensuring that your site runs smoothly. Additionally, if you encounter any issues during updates or installations, you can use tools like WP Rollback to revert to a previous version of a theme or plugin, or troubleshoot by deactivating plugins and themes via FTP or your hosting provider's file manager.
Step 3: Increase PHP Memory Limit
If you see an “Allowed Memory Size Exhausted” error, your site is running out of memory, and you’ll need to increase the PHP memory limit. This is a common cause of WordPress fatal errors, especially on sites with lots of plugins or large media files.
To increase your memory limit:
- Open your wp-config.php file via FTP or your hosting provider’s file manager.
- Add the following line of code just before the line that says `/* That's all, stop editing! Happy blogging. */`:
define('WP_MEMORY_LIMIT', '256M');
This increases your memory limit to 256MB, which should be enough for most websites. Save the file and reload your site to see if the error is resolved.
Step 4: Restore from Backup
Sometimes, the easiest way to fix a WordPress fatal error is by restoring your site from a backup. This can quickly undo recent changes that may have caused the error, like plugin updates or theme modifications.
If you’re using a backup plugin like UpdraftPlus, restoring is simple:
- Go to your WordPress dashboard.
- Click on “UpdraftPlus Backups” under the “Settings” menu.
- Choose the backup you want to restore from and click “Restore.”
If you don’t have a backup plugin installed, check if your hosting provider offers automatic backups. Many hosts keep daily backups of your site, and you can request a restore directly from their support team.
Step 5: Check for Server-Side Issues
If none of the above steps work, the issue might be on your server’s side. Contact your hosting provider’s support team to see if there are any server-related problems affecting your site.
You can also check your server error logs for more information. Most hosting providers give you access to these logs through their control panel. Look for recent error messages, which can give you clues about what’s causing the WordPress fatal error.
In some cases, the error might be related to your server’s settings or limitations. For example, if your site is experiencing high traffic, your server might be overloaded. Your hosting provider can help you troubleshoot these issues and may recommend upgrading to a higher-tier hosting plan if needed.
By following these steps, you can often resolve a WordPress fatal error and get your site back online without too much hassle.
Tips To Prevent Future Fatal Errors
To avoid dealing with a WordPress fatal errors in the future, it’s important to take some preventive steps. These simple practices can save you time and frustration down the road:
- First, always keep your plugins, themes, and WordPress itself up to date. Updates often include security patches and bug fixes that help prevent issues. Ignoring updates can lead to compatibility problems, which can trigger fatal errors.
- Next, make sure to use only quality plugins and themes from reliable sources. Some plugins might not be well-maintained, and poorly coded ones can conflict with other elements on your site. Stick to trusted developers to ensure compatibility and reduce the risk of errors.
- Backing up your site regularly is another essential habit. If something does go wrong, a recent backup can save you from losing your content. Use a backup plugin like UpdraftPlus to automate this process and keep copies stored safely.
- Finally, choose a good hosting provider. An optimized hosting environment with strong support can make a big difference when troubleshooting issues. Your host should offer sufficient resources, such as memory and server speed, to keep your site running smoothly and minimize the chances of a WordPress fatal error.
By following these tips, you’ll significantly reduce the risk of future fatal errors and keep your website running reliably.
