Hello,
Looks like FTP account is for different site because I don’t see our theme in themes directory http://prntscr.com/hvwe9n and there are no plugins http://prntscr.com/hvwfqc that you have in Dashboard http://prntscr.com/hvwg37
Besides, describe me step by step your actions to reproduce the error. If we need to go through this authorization http://prntscr.com/hvwjhw we need FB access to continue.
Regards
