How to troubleshoot Drupal issues

This article discusses how to troubleshoot problems with Drupal.

Troubleshooting Drupal

Drupal is a complex piece of software with many components. If you encounter a problem running Drupal on your site, it can be difficult to know where to begin. Use the following techniques and guidance to help identify and solve problems with Drupal.

Disable modules

Modules can be a source of Drupal problems. By selectively disabling modules, you can determine which one is causing a problem. For information about how to do this, please see this article.

Blank pages or missing content

Drupal may display blank pages (sometimes referred to as the “white screen of death”) or content may be missing. For information about how to troubleshoot these types of problems, please see this article.

Other common issues

Here are some other common Drupal issues and information about how to troubleshoot them:

• Page display problems: If you experience page display problems, or your page edits have no effect, you may need to clear and rebuild Drupal's caches. For information about how to do this, please visit https://www.drupal.org/documentation/clearing-rebuilding-cache.
• Cron job does not run: Your Drupal site's cron job may not run, or it may run incorrectly. For information about how to configure the Drupal cron job on A2 Hosting servers, please see this article.

A few words about performance

Your site may not be experiencing a specific problem or issue, but just running slowly in general. If so, you may want to consider installing the A2 Optimized plugin. It contains several optimizations that can significantly improve Drupal performance. For more information about the A2 Optimized plugin, please see this article.
