[Mailman-Users] Error creating mailing list with http://URL/mailman/create

[Robin Cook]

Hello,

I have just install mailman and everything seems to be working until I
try to create a mailing list using the web interface.  When I click on
the create list button I get this error below.  I couldn't find in in
the FAQ and the archives listed was a bad link.  What is set wrong?
