I can use Iceweasel for BlenderArtist forum if there is not other way. I found also warning when click search icon without query: Warning: Declaration of vBForum_Item_SocialGroupMessage::getLoadQuery() should be compatible with that of vB_Model::getLoadQuery() in …/packages/vbforum/item/socialgroupmessage.php on line 21 Warning: Declaration of vBForum_Item_SocialGroupDiscussion::getLoadQuery() should be compatible with that of vB_Model::getLoadQuery() in …/packages/vbforum/item/socialgroupdiscussion.php on line 21
