Hi, I recently updated the (paid version) GP theme and found that our website menu is not functioning properly. Its reg. the main menu (Shop by Product … etc), the nav space is using up all the screen size, leaving it white. If you hover over the main nav. you will see the result.
Try clearing all caching mechanisms set on your site. I checked and you also have CDN cache. If you didn’t set this up, check with your hosting provider. Ask them to clear it for you. See: https://share.getcloudapp.com/GGuzmNld
