So I often pop in to check threads or quickly look up something in the dictionary using my phone. The mobile version of the site's very easy to navigate and works well. But whenever I go to sign in so I can reply to a thread or something, it doesn't work. If I enter my username or password incorrectly, the site will tell me so I know that's not the issue. When I do enter it correctly it just spits me back out to the main page and I'm not signed in.
Is it just not possible to sign in on the mobile site?
