Summary

WordPress is one of the most versatile applications around. However, due to 3rd party scripts, plugins, and themes, WordPress can occasionally have problems. These problems usually break the PHP process, and a white page is shown with no error.

While the causes of this error vary, there are typically two fixes that will resolve the issue. In the following article, we will demonstrate how to disable all the plugins and reset the theme.

• Increase the PHP Memory Limit

Disabling WordPress Plugins

Account Manager

1. Click the Hosting tab from the side navigation.
2. Select the website that you need to troubleshoot under the Site tab.
   
3. After selecting your site, navigate to the Plugins tab to view your current plugins.
   
4. Click on the toggle to deactivate all of your plugins.
   

Bluerock

1. Click on the My Sites tab from the side navigation menu to the left.
2. Locate the site you want to update, then click the Manage Site button.
   
3. Click the Plugins tab, then click the toggle to reflect OFF for all of your plugins.
   

Now check your site to see if it's working again. If so, you will know that a plugin was the cause of the issue. Your next step will be to go back and enable the plugins one at a time.

Check your website after enabling each plugin and see if it goes down again. If your website goes down after enabling a specific plugin, check with the developer of that plugin for assistance.

If this does not bring your WordPress site back online, try changing your theme as well.

Changing The WordPress Theme

Account Manager

1. Under the Hosting tab, choose the site you are working on, and then click on the Log into WordPress button.
   
2. On the WordPress menu, go to Appearance and select Themes. Choose the new theme you want to switch to, and then click the Activate button.
   

Bluerock

1. Click on the My Sites tab from the side navigation menu to the left.
2. Locate the site you want to update, then click the Manage Site button.
   
3. Click the Overview tab (if not loaded by default); you should see four boxes towards the top of your screen with different management options (Themes, Plugins, User, Updates).
4. Click the Manage button under Themes.
   
5. Scroll down to Inactive Themes, and click Activate on the theme you would like to use. This should deactivate the current theme and use the theme you chose instead.
   

Check your site again to see if it is working. If so, then the likely culprit of the issue was an error caused by your theme. Check with the developer of that theme for assistance, or use a different theme.

Purging Cache

Suppose your website experiences a high volume of concurrent visitors. In that case, it may sometimes appear inaccessible due to the excessive PHP processes running on the server.

To enhance performance, you can enable page caching. Bluehost provides a caching feature through both the Bluehost portal and the Bluehost plugin. This feature is automatically activated for all WordPress installations and is designed to optimize your site's performance.

Enable Debug Mode

Debug mode is an incredibly valuable tool for troubleshooting a WordPress site that is experiencing errors or not functioning correctly. Enabling debug mode allows you to pinpoint the root cause of the issue. This article will provide you with a step-by-step guide on how to enable debugging using the wp-config file.

Increase the PHP Memory Limit

WordPress may fail to load the necessary resources when it reaches its default memory limit, resulting in a blank page. By increasing the PHP memory limit, you provide WordPress with more resources to handle the demands of your site. This can prevent memory-related errors and alleviate the occurrence of blank white pages.
