Display $attachments array from hook_page_attachments_alter() in the messages area of each page.
Display the language-independent machine names of the permissions in mouse-over hints on the Permissions page and the module base file names on the Permissions and Modules pages.
New templates, theme overrides, and changes to the theme.info.yml need the theme registry to be rebuilt in order to appear on the site.
Select the error handler(s) to use, in case you choose to show errors on screen.
  • None is a good option when stepping through the site in your debugger.
  • Standard Drupal does not display all the information that is often needed to resolve an issue.
  • Backtrace displays nice debug information when any type of error is noticed, but only to users with the Access developer information permission.
Depending on the situation, the theme, the size of the call stack and the arguments, etc., some handlers may not display their messages, or display them on the subsequent page. Select Standard Drupal and Backtrace above the rendered page to maximize your chances of not missing any messages.
Demonstrate the current error handler(s): notice, notice+warning, notice+warning+error (The presentation of the error is determined by PHP.)
