Validation Problems Everywhere!

Since moving host the other day, none of my pages (except my main page) will validate. I have the following error:

I am unable to validate this document because on line xxx it contained one or more bytes that I cannot interpret as utf-8

I can’t see anything abnormal, and it was ok before. Please help.
