Squid 403 error
 

I setup Squid and had everything working. Today I reset the computer and instead of getting the Squid error page now when going to a blocked page I get a 403 error. What the heck is going on? I am running 2.5

403 is a forbidden page.

I am fully aware of what the error implies. I am looking for a reason why it is giving me the 403 error instead of the Squid blocked page like it should be.
