Hello,
We don’t see problems directly related to our theme on your website. But there are a few things that you should pay attention to.
1. You can try to apply the solution from this topic to preload our theme fonts as recommended by Pagespeed report https://xtemos.com/forums/topic/preload-key-requests-2/#post-233456
2. Your images are very large even if you use the lazy loading function. You need to resize them and load the correct size.
3. You don’t use CDN on your website.
4. Use our theme CSS generator to reduce the CSS https://xtemos.com/docs/woodmart/css-generator/
5. Pagespeed report says that your server response is slow. But in real tests, we don’t see any problems with that.
6. Try to temporarily disable all external plugins and test how it works without them.
If you see any issues directly related to our theme, please, provide us all the necessary details about that and we will do our best to help you.
Kind Regards
