Hi and thanks for the quick response!
The whole matter had 2 different approach and one part was with you guys and it checked to be all fine, since no change regarding contact form was made to the theme, since the last update. Thanks for clearing that part out!
The other aspect of the matter was with web host and they have been working on the matter due to huge amount of unsecured WP installations and ip bans.
All sis working out now and again, thanks for the help.
Kind regards
M.
