Problem with demo import – broken first page

Hi. After installing and importing demo (it always gets stuck at 67%, even if i set the execution etc on php to 300s) a second time it goes to 100% and the front page looks like its boxed and pushed to the left. I can provide URL and login so you can take a look… I’m installing it on a fresh site. On top of that, I get many php warnings, which I’m trying to ignore.
