i am having a very similar problem.. i entered some code in my page as well.. i put it in header.html.. it messed up my site, removing most of the styles. so i removed it, just reversed what i had done.. cleared the cache's, etc.. on the site and the browser as well, but it is still all jumbled. i had an empty page that i put the code in.. then i went back and removed the code so the page was exactly as it was but the site will still not come back..

clues.. anyone.. please?
