For some reason, I can't reasize the text areas anymore, when I try to add some new content or edit old one. I'm running Moodle 3.9.2 and a second installation with the same Moodle version on the same server is not affected.
I think the problem is related to a warning my browser is giving me, but so far, I wasn't able to find out what it is causing it.
Any reports of similar problems are welcome so that I can find out what exactly is causing it, probably a plugin.
