I have a very weird problem these days. When I browse any blog on wordpress.com (including mine, which uses Andreas09 theme), I find all the blogs seem the same (i.e. missing theme-based formatting) and columns are messed up with posts.
I tried to use different browsers (IE, Opera, Firefox), but I still have the same problem. When I used a proxy to browse some blogs, they looked surprisingly OK.
I cannot imagine how it could be a problem with my PC. But it might be!
