1.Add to cart is not working in quick view. what to do for fix that.

2.even the superstore theme is loading very slow, i checked my website speed in gt matrix, it is around 90%, but on our end, catalog page take too much time to upload

3. when we click on add to cart, it went to cart page, is there any way to keep on that page only for continue shopping, and after all item add in cart, then we will go to cart page.

3. catalog search is also not working fine. if we search any specific product it will not come in first or first page only.
