I had problem with moodle plugin in OM 5.0.0 , because when i tried to access
classroom from Chrome browser it said Invalid Hash Access denied. You have no
rights to enter this room. I didn't have problem entering classroom directly
from server page only from moodle plugin and i had to use Opera browser because
it worked best. Now i installed OM 5.0.1 and when i try to enter through moodle
plugin with Opera the same error occurs like with Chrome Invalid Hash Access
denied. You have no rights to enter this room. Now only Firefox and Edge
browsers are working. I checked everything and i have latest openmeetings
plugin for moodle installed and yes i only open one tab at time but i am sure
that problem is with the plugin because i don't have that problem when i enter
OM directly.
