I'm having some issues with social theme (wp 3.01 and latest buddypress) and the 'invite anyone' plugin - specifically the group part.
In group, send invite tab:
Firstly it displays out of line, at the bottom of the page.
Secondly, in it does not display a list of site members with checkboxes, as it is meant to. On one occasion it brought up a few random avatars and when I clicked one it said 'invitation sent'. But it had not done so.
When I switch to BP default theme these issues do not occur and the plugin works fine, populating a list of members and sending emails.
