If you can log in to your website’s backend, it helps immensely. But as your entire website is down, you’ll likely want to enter it via FTP (or SFTP).

Contact your web host or look through your hosting dashboard to locate your FTP login credentials and ensure you install an FTP customer like FileZilla. This manual on connecting to WordPress over FTP can assist, too.

Enable Debug in WordPress

If you’re having a hassle with WordPress, one of the first things you must do is allow debugging. With debug mode on, you’ll be capable of seeing the various PHP errors going on to your website, and you can use this to hint again at the foundation of the problem.

As you may be unable to access your dashboard, you’ll additionally want to permit the debug log. This will write all PHP errors to a document.

If you need to turn on debugging manually or get the right of entry to the debug log, comply with those steps.

  • Step 1: Connect on your website with FTP.
  • Step 2: Find wp-config.The Hypertext Preprocessor is in the root folder; open it with a textual content editor or IDE.
  • Step 3: Place the following code at the lowest of the report, just earlier than the final message, then keep it near the file:

Debugging is now enabled on your web page, and mistakes may be written to the log. You can find the debug log within the wp-content material folder, named debug.Log.

Look for names of your theme or plugins to factor in them being the reason or references to a selected report. Even if you aren’t sure what to do with these statistics, keep them someplace — they can help you in case you need to reach out for assistance.

When you’re finished debugging, do away with these lines of code.

Roll Back Your Site

When WordPress errors rear their head, restoring a backup may be a brief and clean way out. While it won’t continually solve the issue, it’s worth a shot. If the problem takes place once more, you will be able to retrace your steps over time.

How you restore your website depends on the way you sponsored it. If you operate a plugin, observe the instructions in the documentation. If backups are covered with your host, you’ll probably be able to do it from your hosting dashboard.

Revert to a Default Theme

The crucial errors may sometimes be traced to a conflict inside your theme. The quality manner to test for that is to temporarily delete it and revert to a default subject, which should clear up the problem immediately.

Make sure you back up your site first, as you’ll want a way to get your subject files returned when they’re gone. Simply reinstalling the topic might also motivate you to lose your custom styling.

  • If you’ve got access to your dashboard, this is easy. Go to Appearance > Themes, click on the topic to select it, and delete it in the lower proper corner of the pop-up window.
  • If you don’t see the choice, try downloading and switching to another theme. The safest bet is to try a default topic like Twenty Twenty-One.
  • If you don’t have access to your backend, follow these instructions to revert to a default theme with FTP.

Step 1: Connect to your site with FTP.

Step 2: Navigate to wp-content/themes. You have two choices here: either rename your theme folder (which will allow you to turn the theme back on later) or simply delete it.

Step 3: If you don’t already have a backup theme, manually download Twenty Twenty and place its files into the themes folder.

Your site should now revert to Twenty Twenty. If it loads correctly now, you know it was a theme conflict. To restore your theme files, simply reinstall or change the folder to its original name.

Disable All Plugins

When you’re having critical errors, a plugin is frequently in charge. If you have several or maybe dozens of plugins for your website online, trying to discover the only one with the issue may also appear frightening.

But there’s a smooth way to discover the problematic plugin: virtually turn them all off and notice if that fixes the problem. If it does, permit them one by one till your website breaks again. And there’s the culprit!

To disable your plugins from the dashboard, go to Plugins > Installed Plugins and tick the checkbox at the pinnacle of the listing to select them all. Then click Bulk Actions > Deactivate, which must be enough to turn off any conflicts and restore your website.

You also can click Delete as a substitute to put off their files, though you’ll need to reinstall them manually or restore a backup.

You can then turn them on one by one by returning to Installed Plugins and clicking Activate on each. You can do essentially the same thing through FTP.

  • Step 1: Log in to your site with FTP.
  • Step 2: Open the wp-content folder to find your plugins.
  • Step 3: Rename the plugins folder to plugins_old and verify that your site is working again.
  • Step 4: Rename the folder back to “plugins”. The plugins should still be turned off, so you can log in to your dashboard and activate them individually. If the plugins reactivate automatically, rename individual plugin folders with _old until your site is restored.

Raise the PHP Memory Limit

Even if a plugin or theme is the reason for your broken website, the PHP reminiscence restriction is regularly the real one accountable.

What is the PHP memory limit? Your net server only has a certain quantity of RAM or memory, so WordPress units a difficult limit on how many reminiscences a single PHP script can take in. When this limit is passed, you’ll come upon the white display screen of death or a critical error.

While you don’t want to set the memory limit too high and permit misconfigured scripts to make your web page move slowly, the default price may be too low. Raising your PHP restriction just a bit ought to immediately repair your damaged website.

  • Step 1: Access your site through FTP and open wp-config.php.
  • Step 2: Insert the following code right before the final line and save.

You can also try 256M if this doesn’t fix the issue, but anything higher is unnecessary unless expressly called for in plugin documentation. If the issue is with the memory limit, the plugin you’re using is almost undoubtedly broken and needs to be disabled.

Raise the Max Upload File Size and Text Processing Functions

If you’re most effective at seeing the critical errors in certain conditions and not continuously on each web page, a minor tweak to 3 PHP features might be capable of fixing it.

Uploading large documents and finding yourself on an error screen is probably a result of the max add file size being too small. At the same time, big page breaking can be constant using growing recursion and backtrack limits.

First, test your most add size and compare it to the report you’re trying to add. You can discover this using journeying Media > Add New and checking under the file uploader.

To fix either of these issues, you’ll need to log into FTP and edit the wp-config.php file, placing the new code right above the final comment line.

Clear Your Site Cache

Caching is an exquisite way to speed up your website, and most of the time, it’s strictly a good component. But occasionally, the cache can get corrupted, leaving your site throwing out errors.

When this occurs, an easy solution is to clear the cache, which has to be all you want to remove the problem and restore your site to operating order.

Upgrade Your PHP Version

Outdated PHP can cause your site to break, and other conflicts are sure to occur. You usually want your site on the latest version of PHP supported by WordPress, currently PHP 7.3 to 8.0.

Some WordPress users prefer to stay on PHP 7.4 as they’re concerned about theme and plugin compatibility. Usually, this won’t cause problems. But if you’re using PHP 5.x, it’s imperative you upgrade as it can cause serious conflicts.

Check for Malware

Sometimes, a crucial error can result from malware, mainly if you notice abnormal PHP scripts that can’t be traced back to your plugins or theme. Removing the malware is difficult, so you’re locked out of your website and may not even run an experiment.


WordPress critical errors may have various reasons, although the problem frequently concerns PHP. Either the PHP memory restriction has been exceeded, or your plugins or themes are having trouble.

The fastest manner to restore the trouble is to roll your website over when you have a backup. However, you could attempt numerous other techniques, from elevating the PHP reminiscence limit to identifying and turning off a problem plugin.
