Sometime my site get stuck on
proceed to checkout and
add to cart after upgrading magento 22.214.171.124 from 126.96.36.199
add to cart button does not work. Same in admin when i try to create/save new product. It shows loading then i refresh admin and save again, it saves. It also happening in many events like creating new products, click on order section and cleaning cache. Re-indexing is also taking lot of time.
can anyone help, how to resolve these issues?
