The memory limit is one of the most common errors on the WordPress white screen, mainly because we are using the site and we are not so concerned with the space we are occupying when storing images, posts and other files.

When this error occurs, you can see a message like this: “Allowed memory size of 33554432 bytes is exhausted (tried to assign 122880 bytes) in / home / xyz… ..”.

This means that your current theme, or any plugin you downloaded, for example, has exceeded the memory limit that was available for you to use.

Problems with plugins

It is very common that any update of one of your used plugins can lead to the white WordPress screen. This is because the changes of the new version installed, may not be compatible with all other configurations of your site.

Therefore, when this error occurs, it is important to gradually disable your plugins to identify whether one of them is causing the white screen. You need to do this one by one to make sure you find the culprit.

Once you find it, keep it disabled and contact the developer so they can help you resolve the issue. This way, you will definitely not lose use of the plugin.

Themes issues

The same can happen with your WordPress theme. If it is updated, or undergoes any changes to its original configuration, it may have a major impact on your site, leading to a white screen error.

If everything goes back as before, it is necessary to contact the person responsible for the development of the chosen theme, so that he can help to configure it correctly. You can also open a support help ticket in the WordPress repository.

In the meantime, it is possible to use a standard theme indicated by WordPress itself so that your website continues to function normally.

Syntax problems

If you have tampered with or changed your WordPress code with something that is out of place, it is possible that your site will have a white screen.

Fortunately, it is possible to reverse this situation manually by connecting your website using SFTP which, in addition to solving this issue, can do everything very safely.

As we can see, the error of the WordPress white screen can even give a scare to the administrator or users when it occurs, but it is certainly much easier to solve than it seems at first.

Just carefully investigate and perform the procedures indicated above, one by one, to identify exactly what the error is and correct it as soon as possible – in a safe way!
