Cannot access advanced parameters/modules

[Brandon Looi]

Hi guys, for the version I'm using Prestashop 1.7.3.4/1.7.3.3 both of them are having the same issue. Since I was on Apache2, the backoffice is loading extremely slow, so I thought to myself to change to Nginx, after that I've hit a couple of problems already ,such as the Modules/Advanced parameters, whenever you click on them, it just brings you back to the front office, whereby the others are working fine. I'm not sure if it has to do with Nginx's rewrite or something.. but is there anything we can do?

As for the Apache2, the backoffice is really loading extremely slow, how do i add more products with every pages taking up more than 5s to load? Thanks
