Hello,
We have tested the product category of the site that you provided access to https://mohsha91.dreamhosters.com/pc/grocery-staples/ We got the following results: with XStore theme – 3.7s https://gtmetrix.com/reports/mohsha91.dreamhosters.com/u2vBEx8j https://tools.pingdom.com/#5cf5fb2cd1c00000 with Storefront theme (default WP WooCommerce theme) – 3.3s https://gtmetrix.com/reports/mohsha91.dreamhosters.com/sTQpk4AC https://tools.pingdom.com/#5cf5fbe3b4800000
So, as you can see the difference between loading of the site with the default theme and our theme is essentially nonsubstantial.
But another link you provided http://mohsha91.dream.press/pc/grocery-staples/ has completely different results. It means that something is different in site settings and in server settings. Compare plugin and server settings of these 2 installations http://mohsha91.dream.press/pc/grocery-staples/ and https://mohsha91.dreamhosters.com/pc/grocery-staples/ to find out why the first one has bad results.
You wrote about server cache issues with our Core plugin. Could you, please, explain in more details what errors do you get? What part conflicts with the cache? Maybe provide screenshots for better understanding.
Regards
