I’ve narrowed it down: it’s a problem with having a tag. I looked at a post I managed to edit this morning: no tag. Added a tag: error. Removed the tag: saved.
With the help of my AI assistant (thanks PAI!) I’ve figured this much out:
- Safari only (works in Chrome)
- In safe mode with themes and components deactivated: works
- Different theme: works => Air Theme is probably the issue
