Tenho o squid instalado e o apache mas quando digito o endereço para a página do apache, esta dando este erro:

"
ERROR

--------------------------------------------------------------------------------

While trying to retrieve the URL: http://lasertest-serv/manual/new_features_2_0.html

The following error was encountered:

The system returned:

E antes não dava este erro, o que pode ser?
