Remember Me cookie and Invalid Redirection after login

Up until a week ago, the remember me cookie was working just fine. Now pretty much every day i have to re log in my credentials. About half of the time i sign in I am redirected just fine back to the main site, but the other half I am sent to a page that says I had an invalid redirection.

Not a big deal but if other people are seeing it too thought i would bring it up.

Chrome Version 26.0.1410.64 m
Windows 7

That appears to be the problem.

I noticed it a few days before i posted so the 10th makes sense. I had always accessed the site in the past without www sub domain being added (used to most sites just adding/redirecting it if they need it).

As for the mobile css and so forth that bhuwan is talking about, I cant say since i dont have a mobile device.
