Hello,

Thank you so much for purchasing our theme and contacting our support center.

Yes, we see that your server returns 404 error from time to time on AJAX requests. Here is a screenshot https://gyazo.com/5a4e5ea8b39a1f67e2f00b5a0c4299a0
We checked the error logs but don’t see any records there. You need to contact your hosting provider and ask them why this request can’t be complete. Maybe there is a timeout limit or error there but we can’t know exactly without any error logs.

Kind Regards
XTemos Studio
