Thank you very much for choosing our theme and for contacting us.
Please, provide your site admin access (insert the site credentials into the Private content block under the message area) so that we could check deeper.
The problem is 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 you have any questions please feel free to contact us.
