Hello,
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).
We will check the WordPress Settings > General and Permalinks.
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.
Best Regards
If you have any questions please feel free to contact us.
Best Regards
