How to Fix WordPress Blank Page (White Screen)?

If there is a problem with WordPress, you could see the White Screen on your website. There will be broken or incomplete parts of your website, which is what initially causes the white screen to appear. It usually happens when there is a problem with your website’s PHP code, which is WordPress’ programming language.

We will talk about the issue in brief in this article. Along with the remedies to address the White Screen, we will also explain why it occurs.

Now let’s get going!

What is White Screen?

White Screen error, as the name implies, is a simple white screen that appears when you enter your website instead of the content. It might happen on a section of the website or the entire thing, including your admin panel.

There are several different problems that might be causing the White Screen to appear. When that happens, your website will usually have some damaged or missing sections. Most of the time, a plugin or theme with improper code or one that conflicts with another area of your website is the most likely culprit. Inadequate memory or server problems might also be the cause of the white screen.

Techniques to Troubleshoot the WordPress White Screen

White Screen displays a blank page that does not give you any clues about the problem. We have listed a few common remedies to resolve the error.

Note: Before proceeding, we recommend you take a full backup of your website as you may have to make a few changes to it. The techniques we will discuss here may solve the issue. But, they can also affect the original appearance and functions of your website.

1.  Clear Cache

Clear the cache of your browser and reopen your website.

If the error still persists, log in to your WordPress admin dashboard and flush the cache of your plugins. Remember to carry a scheduled caching of your plugins, or it may affect your website in other ways than White Screen.

2. Check the Error Log and Enable the WordPress Debug Mode

If none of the methods mentioned above worked, the issue would probably be in the coding of your website. It is something only a developer could solve.

You will have to access the WordPress Error Logs and enable the WP_DEBUG mode. It will give the location of the coding error and bugs on your website that may be causing White Screen.

Remember to disable the debug mode after you are finished. For this, edit the wp-config.php file, and change the WP_DEBUG line back to false. If you mistakenly leave this mode activated, it can lead to huge problems and security issues, so always ensure to close it down after you complete troubleshooting.

3. Check Your Memory Limit

White screen is a sign that your website has reached its maximum memory limit if it appears sometimes or just in certain areas of your site. It speaks about PHP memory, or the amount of memory allotted to the PHP operating system that powers WordPress. Basically, the 64MB limit is the default setting, but occasionally you need more.

It is immediately possible to raise your WordPress’s memory limit. Since your servers do not have infinite resources to spare for a single website, try to set the disk space value reasonably.

It is advised that you raise the RAM limit by 10MB each time to see whether it resolves the problem.

There are cases when you would have to increase PHP Memory Limit using htaccess.

4. Switch PHP versions

At times, the white screen will appear if the website uses the incorrect version of PHP. Try changing the PHP version of your website.

5. Activate/Deactivate Your Plugins

One of the most common solutions is to disable your plugins. By doing this, you can determine whether the plugins are an issue or not after reloading your site.

In case your site starts working like usual after deactivating your plugins, it means one of the plugins is causing the problem.

So, re-enable them one by one and test the site after you activate each one. In this way, you can detect the faulty plugin as your site will go down as soon as you enable it. After this, disable or deactivate the plugin and contact the developers for further support.

Don’t forget to move all the working plugins into the plugins folder after completing your search for the faulty plugin.

6. Investigate Your Theme

If your plugin is not the issue, it is probably the theme that is causing the White Screen. Try disabling your current theme and change to a generic theme instead.

Access the admin dashboard and go to Appearance > Themes. Just move to one of the default WordPress themes, such as Twenty Seventeen, and click Activate.

If you are unable to access the admin dashboard, use SFTP to troubleshoot this problem. Double-click the wp_content/themes folder and rename it for the theme you are currently using.

After this, WordPress will deactivate your theme and automatically apply the default theme instead.

7. Check If Your Server Is Down

Review the service status of your host server by contacting your provider. There is a rare chance that some of the server elements are not functioning normally or are down for maintenance.

In any case, if everything fails, you should still contact technical support and ask for help.
