Hello,
Thank you very much for choosing our theme and for contacting us.
The problem may be caused by incorrect HTTP and HTTPS configuration: https://domain.com is the actual site URL, however, http://domain.com is used in Dashboard > Settings > General. In this case, it is necessary to configure URLs correctly.
If the URLs are configured properly and the problem remains, please insert the credentials into the Private content below the message area.
Best Regards
