Sure, first Marie added Steffen as her Boyfriend, it told her it was awaiting his approval. He never got a relationship request. Then he tried to add her, she never got a relationship request. It seems the relationship plugin is broken, because I have seen others complain here on the forum.
In terms of EasyDiscuss, well, he got these errors when opening EasyDiscuss (Refer to screenshots), I fixed them by disabling Show Custom Fields under the Tabs section in the admin menu. After that he could not see his own custom role badge (COO). They might work now, not sure, but he complained about 2 or 3 things, that no one else has experienced, so I figured his account might have a corrupt database.
