Hello,

Thank you very much for choosing our theme and for contacting us.

Please follow these manuals and let us know if the problem persists: https://xtemos.com/docs-topic/adding-menu-to-the-site/ this manual provides instructions on how to add a menu.

This manual provides the instructions to create mega menu: https://xtemos.com/docs-topic/create-mega-menu/

If something does not work as it should, confirm the permission for plugins deactivation, and switching to the parent theme. As soon as we complete the testing we will enable all back, however, the site would be without plugins for 15-20 min. You would better make the full backup of your site.

Best Regards
