I have a website that is pretty much just css, html and php. I have incorporated a membership and log in system. For some reason in Internet Explorer, when users log in, the page becomes distorted (higher line heights, misplaced images, etc.). But it's only when they're using Internet explorer and logged in. If you are running other browsers or you're not logged in, everything appears fine. It seems to me that perhaps 'session' has something to do with this? Does anyone have any idea?
