Live website not updating/reflecting the changes

I was able to create a clone of a website and get it to work but I’m now facing issues with accessing Grav admin. The domain.com/admin doesn’t work.

I did not install the default (out of the box) Grav installation but rather just went with the already existing Grav installation.

Could this be the reason why I can’t access the admin?

I’ve read here that I should rename the domain folder inside of /user/ but there’s no user/env/ or user/domain.com/ folder inside of my Grav installation.
