Do you know which files you have modified?
The info provided by the validator can appear rather daunting, but all you need to do is view your Page Source and refer to the line numbers given by the validator for each error. You should then be able to work out, from the position of the error in the Page Source, whether the error is in a theme template file or your post content. Does that make sense?
