Too many negatives inside your brackets, please clarify...

I find that hard to believe...

No, can't see that helping here.

Again, irrelevent here.

Ah, so you're exposing Zope to the big wide internet without a 
protective proxy like Apache in from?

d'oh.

Read the error message. People are trying to hack your server. Zope 
tries to prevent against it, but I'd still stick a defensive proxying 
configuration of Apache in front and see if the problem goes away..
