Hard to tell. Are your links correct (sometimes the browser will interpret a 'wrong' link, and sometimes they won't)? Check your page source and make sure they are all correct.
i dont know. we are using 3.8 beta 4 and we have not really messed with the template much especially nothing to do with the login. I tried resetting the template andd still had the same problems. I know we didnt have this problem before we moved from 3.7
