Can't select anything in top 30% of screen

I can’t select anything in the top part of the screen. Not in normal, drop, paint nor view mode. Any solution?

It doesn’t work with the mouse and keyboard shortcuts

Never seen this before. Perhaps make a small example and add it here, so we can try and see for ourselves?

The strange this is that it only happens with just one project. My other projects and new ones work just fine. It’s only 3 pages now, so I guess I’ll just remake them in a new project.

Could be a custom class.

probably, just removed html widgets and everything seems ok

If you are pasting in anything other than plan HTML in those it could break.

I’m just embedding another page (map in leafletjs) which indeed uses js.
