What is Critical Error in WordPress?

WordPress’s critical error is one that prevents it from loading all the scripts it requires to function properly.

In the past, this WordPress problem would display a fatal error message or a white screen of death. Most novices struggled to tackle the problem on their own and didn’t find it particularly helpful.

What Causes the Critical Error in WordPress?

The crucial WordPress issue is typically brought on by a broken plugin, script, or piece of code that prevents WordPress from operating correctly.

If you don’t fix this problem, WordPress won’t be able to load the other files it requires.

The critical issue could be brought on if you recently copied and pasted code from a tutorial onto your website.

Since all of the best WordPress plugins have undergone extensive testing, they are less likely to independently create a serious issue. However, the problem could be caused by a clash with another WordPress plugin or by some custom code.

Having stated that, let’s look at how to quickly remedy the serious mistake in WordPress and restore your website.

On the other hand, you can just adhere to these guidelines if you are hesitant.

1. Deactivate All WordPress Plugins

Deactivating a problematic WordPress plugin is the simplest approach to disable it. You are unable to access the admin area because of the serious error, and you are unsure of which plugin has to be deactivated.

We will turn off all WordPress plugins to address this. Don’t worry; once you have access to your WordPress admin area, you can quickly reactivate them.

After connecting, you must find the /wp-content/ subdirectory.

There is a folder called “plugins” inside the wp-content folder. You must perform a right-click on it before choosing the “Rename” option.

Next, give the plugins folder a new name of your choosing. We’ll refer to it as “plugins.deactivate” in our example.

All of your plugins will be deactivated when you do this.

In order to load the activated plugins on your website, WordPress essentially searches for the plugins folder. Simply said, it is unable to activate the plugins and puts them as deactivated when the plugins folder is not located.

Simply go to themes directory and download a fresh copy of the TwentyTwenty or Twenty Twenty-One WordPress theme.

Next, you need to unzip the theme file to your computer. This will create a folder with the theme name on your computer.

Go ahead and download all of them to your computer as a backup. After that, you need to delete all theme folders from your website.

Your WordPress site now has no theme installed. To fix this, go ahead and upload the default theme folder you downloaded earlier.

Try viewing your website once you’re done.

You should now be able to access your website if the critical problem was brought on by your WordPress theme.

The critical WordPress issue could potentially be caused by malware or a faulty WordPress core file. Reinstalling WordPress is the simplest fix for this.

Select the files on your computer located in the wordpress folder, and then upload them to your website. Your FTP client will ask you if you want to overwrite or skip these files. Choose “Overwrite” and make sure the “Always use this action” checkbox is selected.
