Hello, Zeal Evince,
Thank you for your response.
1/ We can see js errors from different plugins on your site. You have a lot of plugins activated. Please check descriptions of every plugin and disable plugins you do not really use because every additional plugin slows down the site a bit.
For example, disable YITH WooCommerce Compare and YITH WooCommerce Wishlist and use our own functionality from Theme Options > WooCommerce https://youtu.be/ZyjZ-vCx0pE
2/ Your problem when WP Rocket plugin is activated can be caused by incompatibility with a 3rd party plugin. Please do a test to check it – disable all third-party plugins that are not bundled with XStore. You can refer to the following link for a list of included plugins: https://xstore.helpscoutdocs.com/article/36-included-plugins , and check how it works then.
We use Rocket on our demos without problems.
3/ You need to optimize images https://tinypng.com/ and follow this article also – https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website
4/ We’ve enabled Lazy loading in settings or Products elements on your Home page – https://prnt.sc/v0xJ_h5dWgJZ
