Description:
------------
I was trying to add a note in http://ca3.php.net/manual/en/configuration.php
but the challenge thing "Answer to this simple question (SPAM challenge):" does not work.
e.g. max(eight, one) every human will report "eight" but the program said "Challenge Failed" and my note is not published.

Reproduce code:
---------------
try to add a note under some function e.g. http://ca3.php.net/manual/en/configuration.php

Expected result:
----------------
My comment to be published :)

Actual result:
--------------
error for failed challenge + my code should roughly look like that.....
