Just to make things easier for you if either a WordPress plugin or a Simple:Press plugin causes problems then rather than go through hoops deactivating and reactivating, as an ’emergency’ measure, the quickest course is to simply remove the plugin’s folder. Not rename it it but remove it. So – in this case remove wp-content/sp-resources/forum-plugins/buddypress – which should then allow things to continue as they should.
Back to the error log if we may. A 500 server error would normally put an specific entry in the error log. Are you seeing no actual item marked as a 500? Or – I will have to check with someone who knows – maybe the error only gets written out to the server log as opposed to the php log. Can you check that? (Usually from the hosting control panel).
