I have been using this login 'template' for a while now on one of my websites that have no SSL certificate.
When I was trying to setup the same login template on my site that has RapidSSL, it gives me a 403 error when I click the login button. It's connected to the same database and the files are the same so it shouldn't be a difference, really.
Does having a SSL certificate complicate login websites somewhat?
Tried using it on another site that has no certificate aswell and it worked fine.
