There seems to be a cache problem on one of our sites. v 1.7.8.6
We keep on getting customers messaging saying they are unable to proceed to cart.
When they click "Proceed to cart", it directs to the homepage. If they clear their cache, then "Proceed to Cart" works correctly.
We as B.O user also have problems logging in sometimes. We enter the correct login details and click "Sign in", the login page reloads without any "incorrect credentials" and doesn't direct to the B.O. I first tried to "Clear cookies" and that didn't let me log in, but after "Clear cache" then it logged in fine.
We are on a plesk server running linux, PHP 7.4.30, MariaDB 10.1.48
Any help appreciated
