Last Updated on 27th November 2022 by Ajmer Singh

What is Fatal Error in WordPress?

WordPress is a CMS (Content Management System) with many different versions that boast its high flexibility and functionality.

The most famous of these is the self-hosted version, which gives users complete control over their website content.

If you’re using WordPress to power your site, then you can easily update your site from a single interface.

Using a plugin or a theme? You too can update those as well within the admin panel!

However what happens when something goes wrong? What if there’s an error? Well for one, it disrupts the smooth running of your site.

But another issue might arise: being hacked.

In this article, we’ll discuss some errors that may arise with WordPress instances, as well as how to fix them.

Some WordPress errors are fatal.

A fatal error usually causes the crash of the application, which can cause serious damage to your site.

If you happen to face this problem, it’s important to fix it as soon as possible.

Here are 5 ways to fix it:
1. Update

Update your WordPress version.

Sometimes updates will be released that resolve these errors. Be sure you’re keeping up with them!

However, if you are using Cloudways then they can automatically update to the new wordpress version.

Cloudways is a managed cloud hosting platform that I use on this website.

2. Double check

Make sure all plugins and themes are compatible with each other and your current WordPress version (if applicable).

Make sure they’re up-to-date too!

Check their documentation websites for more info on compatibility or updating instructions if needed.

This is especially important if you bought a premium theme or plugin.

However, I am using the themify ultra theme on this website and there are no conflicts happened till now.

So I recommend using this theme without any second thoughts.

3. Deactivate

Disable all plugins and themes, then re-enable them one by one until you find the culprit of the error.

Remember to test after enabling each plugin/theme to see if this resolves your issue,

else it might be a problem with another third party software on your website or server causing conflicts with WordPress.

4. Reboot

Sometimes glitches are caused because of problems, rebooting properly due to large websites taking a long time to load across many servers

(or even worse! Is your server overloaded?)

If this is the case, you’ll need to contact your web host and ask for assistance in fixing these issues so that they don’t happen again.

This could cost some money as well.

That’s why I recommend using managed hosts where you don’t need to pay for any assistance.

5. Rollback

If you’re running a previous version of your website, for example, if the site broke after an update and caused fatal errors,

then rolling back to a previous backup before those updates can be very effective in saving your current website.

This is not advised though because it may introduce older bugs and vulnerabilities and also new ones that weren’t there on the old version, so only rollback when absolutely necessary!

Cloudways offers free backup to every package.

In short,

what is fatal error in wordpress

1. Update – update the WordPress version.

2. Double check – make sure all plugins and themes are compatible with each other and your current WordPress version (if applicable) & update them too!

3. Deactivate – disable all plugins and themes and enable them one by one.

4. Reboot – sometimes glitches are caused because of problems – rebooting may help.

5. Rollback – if you’re running a previous version of your website, then rolling back to that can be very effective in saving your current website!
