Problem with registration

Hi.
Have some issues with registration

http://www.trep.se/index.php?option=com_content&view=article&id=3162&Itemid=333

Warning: get_object_vars() expects parameter 1 to be object, array given in /home/21327-11869.cloudwaysapps.com/ramkvzvjsq/public_html/administrator/components/com_easysocial/tables/registration.php on line 277

This have worked before. Update to j3.4 might have caused this or trying to enable and disable facebook login.

Please advice...
