I am not sure what is going on but I get this at the top of the screen when I go to Advanced Search.
Warning: Declaration of vBForum_Item_SocialGroupMessage::getLoadQuery() should be compatible with that of vB_Model::getLoadQuery() in ..../packages/vbforum/item/socialgroupmessage.php on line 261
Warning: Declaration of vBForum_Item_SocialGroupDiscussion::getLoadQuery() should be compatible with that of vB_Model::getLoadQuery() in ..../packages/vbforum/item/socialgroupdiscussion.php on line 337
The Advanced Search will not work in FireFox or Water Fox, it does work in IE 11 but the 2 lines of code are still at the top of the page.
Just thought I would let you know.
