Hello! I just upgraded from 2.1.0 to 3.0.7 and strange issue appeared. Every time any user enter any (public or private, does not matter) room an invitation popup opens. It looks like in screenshot - https://monosnap.com/file/sHZDYSapZIExLCO3nLtWirIrWX00V2 I tried to create new room/new user (both ldap and local) - does not matter.
Is it feature / bug and how can I disable / fix it? I'm using openmeetings with mysql backend on debian jessie and java is 1.8.0_73. Users are logged in via LDAP (Active Directory). Client browser is stable Google Chrome on Windows 7 and OS X 10.11.
