When adding a new Topic / Thread to a Forum if the "New Topic +" button is used to add one, it works fine.

However, if someone tries using the "Add New / Discussion" Button on the right of the page, it does not work, it returns the following error: 

OW-Debug - Error

Message:Argument 1 passed to FORUM_BOL_ForumService::addTopic() must be an instance of FORUM_BOL_Group, boolean given, called in /home/autogone/public_html/texasboudoirphotographers/ow_plugins/forum/controllers/add_topic.php on line 184 and definedFile:/home/autogone/public_html/texasboudoirphotographers/ow_plugins/forum/bol/forum_service.phpLine:1155

---------------

Please advise.

Thanks!
