Hi,
Finally I found what is causing this issue. It is about calling the fields value container which is modified in your last version and at least I expect you gave me some hints about it because I, as an user may not trace all of applied changes in every new version.
This is a sample of this conflict :
get_comment_author()
is changed to
esc_attr( $commenter['comment_author'] )
and so on.
Kind Regards
Omid
