Public pages blank but others can still view them?

Hello,

I am currently in a confusing dilemma. Somehow none of my public pages are showing up in my browser. The pages are blank. But when I went to w3.org to check the validity of my coding, the pages were fine with minor errors. The index page didn’t have any errors. Also, one of my friends were able to leave a comment on my site, so I’m assuming it must be visible to her. I tried changing themes, deactivating all my plugins, and I even tried upgrading to v2.0.6. The admin pages still work for me, and I can still create new pages and posts, but I’m unable to view them. I’ve had this problem for three days now. Also, my feeds contain errors for some unknown reason. I’m unsure if that has anything to do with public pages not showing.

If anyone is able to help, that’d be awesome.
