Pay close attention to the following changes if you do upgrade to the new version. I would recommend just going through all the steps again and copying the updated templates.
Templates were renamed:- SHOWROSTER stayed the same.
- showroster_usergroup was renamed to showroster_header
- showroster_usergroupbit was renamed to showroster_userbits
Variables in templates were renamed:- In SHOWROSTER: $usergroups was renamed to $rosterheader
- In showroster_header: $usergroupbits was renamed to $rosterbits
Sorry for any confusion but I'm trying to fork away from the showgroups page.
