Bug reports

While localising all Drupal CMS site templates we found bugs in Drupal core, Canvas, the Drupal CMS installer, the templates and their themes. Each of them has a report in the drupal.org issue format, ready to be filed with the project it belongs to. The Filed column links the issue or work item in that project; a dash means not filed yet. Projects that keep their issues on git.drupalcode.org get the reports as work items, the others through the drupal.org issue queue.

Below each report there is a collapsible "Copy to drupal.org" box with the title and the text as ready-made HTML. The copy button in the top right corner of each block takes them straight into a new issue. The "Filed on drupal.org" checkbox in the "Status" row of each report ticks off the reports you have filed; the tick is saved in your browser only.

Found with Drupal core 11.4.7, Canvas 1.12 and Drupal CMS 2.2 (September 2026). Before filing, search the project's issue queue: if an issue exists already, the details go there as a comment.
