please turn off all extra plugins first. If this won't help, then please send us private message with dashboard and FTP access.
Thanks for posting this. I'm not able to fix this from

defining your own mfn_remove_recent_comments_style which does nothing:
function mfn_remove_recent_comments_style(){}
