I updated @sbrajesh ‘s Limit Groups Per User though don’t know if he is active on the bp forums, if there’s no reply I’ll let him know on buddydev.
Here’s the amended code: http://pastebin.com/q4tzf3Lx
line 19: is_site_admin -> is_super_admin
line 32: BP_GROUPS_SLUG -> bp_get_groups_root_slug
Regarding @dwenaus ‘s BP group tags – It’s also using BP_GROUPS_SLUG and should be amended. Ill happily try it out later if dwenaus is busy. I did report the errors to him in the group tag’s forum though have yet to get a responce – failed to mention to him that using custom groups slugs is causing the issue.
