bug cache???

Hi,

I have errors that it doesn't exists. The validator says me that I have
errors of labels that I erased 1 week ago and it doesn't refresh. I deleted
all my cookies, and everything, and I test in differents places and
computers and it says me again the errors that I tested the first time.

My web is: http://uf3m9.byethost9.com/

Thanks!
