Essential Debugging in Drupal: Displaying Errors & Inspecting Variables
Troubleshooting Drupal can be a frustrating task when errors are hidden behind blank screens or obscure logs — but all of that changes with the right tools and configuration. In his blog post, Ivan Zugec guides you through how to display error messages in Drupal CMS and introduces essential modules and commands for uncovering issues swiftly.
The article dives into practical techniques: enabling error reporting (via UI or Drush), using the WebProfiler toolbar for execution insights, and employing modules like Devel and Kint to inspect variables. It also covers how to use dump()/dd(), debug theme variables in Twig, and switch into full step‐through debugging with Xdebug — providing a clear path from simple error display to advanced debugging workflows.
