[Mediawiki-l] Problem with user page, talk page, other pages, not displaying

[Norman]

Dear Mediawiki support folks;

Hello.  Please, I need help.  I installed and have mediawiki up and running.
Problem is that the admin (or user) and My Talk links at the top of
the page result in an error message via both IE and FF. So I guess
that means there is a problem accessing or creating my pages. This
happens whether I am logged in as admin or as another reader/user that
I created. I also notice that a few links on the sidebar have the same
issue; namely community portal and current events (those links were
installed in the default installation).

On IE, I get a "page cannot be displayed error"

On FF, I get the following error: "Corrupted Content Error The page
you are trying to view cannot be shown because an error in the data
transmission was detected. The page you are trying to view cannot be
shown because an error in the data transmission was detected.Please
contact the website owners to inform them of this problem."

Can someone help or shed light on this? I really would like to get
this operating right and am at a loss, struggling big time. :-(

Thank you in advance,
