I'm having the same problem on my Galaxy S5 using the chrome browser, which is the only one I have on my phone. I cleared the browser history, cookies etc but the site formats for a desktop and not a mobile device and won't even let me pull up my profile or sign in. I too view the site mainly on my phone. I'm using an android phone. Stock android web browser. Samsung Galaxy S4 I fixed the problem on my phone: I had to set the "theme" at the bottom of the page to "Default". Once I did this, it formats correct for a mobile screen.
