Hello, @Behrang,
Your provided WP Admin Login details are not correct/working: https://postimg.cc/kVGsVTCW
And please try to turn OFF the Ajaxify from the theme settings and check back.
You will find it under XStore >> Theme Settings >> WooCommerce >> Shop >> Shop Page Layout as showing in this screenshot: https://postimg.cc/V587gBWP
And then check back your site after clearing the cache and let me know the result.
Regards 8Themes Team.
