2.No one is able to join the group

Thanks for your report. The plugin is a bit complicated and as I found out many things depend on how developers implemented their JS ans CSS adding logic. Could you please contact me by PM and provide more info on issues you have. I'll try to settle them as soon as possible.
Sorry for the delay, I was a bit busy last days. Sent you a message via PM.
Conflicts with G+ plugin styles are resolved. The plugin will be updated by the end of this week.
