Hello, @xyz,
I have again checked your site now and found that still, you are using many third-party plugins, and you did not deactivated them.
And also I can see you are using a lot of Customization code in your Child Theme which might also be generating the issue on your site.
So I suggest you to please reach out to your developer and ask to check the Child Theme Customisation for you and fix it for you as well.
Regards 8Themes Team.
