Ok that definetely worked! That's one problem solved! Thank you very much.
Still the problem with chrome stays. You mentioned earlier about this fix
https://issues.apache.org/jira/browse/OPENMEETINGS-2202 . Does this
address incorrect hash problem for chrome? If yes what should I do with
this? Sorry for asking suck a newbie questions, I'm fairly new to system
administration in general. If you need validation that I'm accesing om
rooms from moodle having only 1 om tab opened I can record a video. I can
also ask my colleague to make the video where he succesfully logs into the
room in chrome using the exact same moodle user.
