I used view source on the link above and it looks like the problem lies in config.asp around these lines:
orMail")
strShowPaging = Application(strCookieURL & "strShowPaging")
strShowTopicNav = Application(strCookieURL & "strShowTopicNav")
strPageSize = Application(strCookieURL & "strPageSize")
strPageNumberSize = Application(strCookieURL & "strPageNumberSize")
strForumTimeAdjust = DateAdd("h", strTimeAdjust , Now())
strNTGroups = Application(strCookieURL & "STRNTGROUPS")
strAutoLogon = Application(strCookieURL & "STRAUTOLOGON")
ReadModConfig()
if strSecureAdmin = "0" then
Session(strCookieURL & "Approval") = "15916941253"
end if
on error goto 0
if strAuthType = "db" then
strDBNTSQLName = "M_NAME"
strAutoLogon ="0"
strNTGroups ="0"
else
strDBNTSQLName = "M_USERNAME"
end if
%>
The code above should be at the very bottom of your config.asp file.
I would guess that right before orMail") there is a %>
