Hello,
1) BE ATTENTIVE and don’t place the private information in general message area because all the visitors have access to that information! Use the Private content area http://prntscr.com/srjgm6 to provide private info.
2) When we follow the link you provided we get 403 error http://prntscr.com/srjfv5 Do you have any limits for the connections from the other countries? Any black list?
3) Provide us with FTP access to your site. We need to enable WP debug and then make changes in theme files to fix the issue depending on the errors you provide. We won’t be able to help you without FTP(or SFTP) access.
4) Provide us with server error logs that you get on your site while enabling plugin + our theme.
Waiting for your reply to proceed.
Regards
