Okay so my site http://www.hola-china.net/wordpress looks fine, that is until you open it in IE- then it looks like a cat through a shredder.
SO.. I went ahead and tried to validate it- and this comes out:
Sorry, I am unable to validate this document because on line 297 it contained one or more bytes that I cannot interpret as utf-8 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.The error was: utf8 "\xE1" does not map to Unicode
