This error relates to the dp_messages_send_message() function in Welcome Pack, which is a copy of BP’s messages_send_message(). My version of the function is a copy+paste with a “from user_id” argument added and lots of code that won’t get used commented out. Trac https://trac.buddypress.org/ticket/673 relates.

It’s the messages_add_callback_values() that the OP’s error is referring to in bp-messages.php. I’m not sure why this error is triggering for some people but not others. It might be custom theme related. Need help!
