I have a strange problem. I had been using moodle 3.8 for the last 2 months without any issue with teachers and students, but suddenly when I and my other admin try to access Course Participants, we get the screen with the Participants title only without any list or button to enroll new users, and also appears the gear icon which I press but the dropdown menu doesn't come out,
I restarted Apache, the whole server, I searched for last modified files in case I've been hacked, but everything seems normal so far.
Also I have to comment that when I'm in that particular page, the dropdown on my profile picture also doesn't work when I click it
I checked php error log, but no strange messages found
Has anyone come across this problem?. Pls. advise.
