From your output:
[11/May/2009:15:22:46][79655.16785584][-main-] Notice: conf: [ns/server/NotFoundResponse]enabletclpages = 0
In the line above, "NotFoundResponse" should be your server name. I doubt, that you are using such a strange name, but who knows.
How do you specify the section including enabletclpages? ns_section "ns/server/${server}"? If yes, how do you set the variable "server" in your config-file?
