I have a fairly high number of forums and groups on my phpbb forum. When i import forum permissions i notice they are not exactly like phpbb.. Am i doing something wrong or is this just a phpbb/xenforo limitation that cannot take place automatically?
XenForo does a best guest import of permissions, since they cannot translate 1 to 1 into XenForo. You should go through all your permissions and verify they are the way you want them.
