I have a login box on a sidebar on the website I'm working on. Normally, there's no problem there. However, when I try to login to the same website using the same credentials on a mobile device, the login just won't work. After clicking "Login", it just goes back to the login page.
The login steps for the desktop and the mobile are not the same though. For the desktop, it's the login box I mentioned above. For the mobile version, it's a link to the "Login form" that I put on the navigation menu.
I thought they ran on the same engine but logging in on a mobile device just won't work. I don't know where to start looking for the solution or what I did wrong. Help, please.
