Fixed tabs breaking after a block was deleted (v4.104.9)
Deleting a block and then adding a page’s first tab before the undo message closed could leave the tab pointing at the deleted block, with only a “Could not find block with id” message and no tab bar. Deleting a block now removes it from every place it’s listed.
If a page already refers to a missing block, editors see a banner in its place with a Remove Block button, and viewers see nothing. The Doctor also removes missing blocks from page tabs, so drafts already saved in this state load normally.
Doctor appears in the settings menu for Contributors (v4.104.9)
Contributors could open the Doctor but couldn’t find it. It now appears under Settings > Tools > Doctor for every role that can use it, and in the app menu and command bar.
