Front Page is messed up

Hi,

I just checked my website today and the front page is all messed up, while the other pages are working fine. The login screen is also messed up, and when I enter my login information, it says page not found. I’m not sure if it’s only happening on my computer, but I cleared the cache and cookies for the web browser and it’s still the same. Please help, thanks!
