I was trying to convert the show_bug page to XML format by adding
"ctype=xml" to the url and it worked. However, when I tried to add the
"excludefield" parameter to the url. It didn't exclude anything.

The url looks something like: show_bug.cgi?

This work on the https://bugzilla.mozilla.org/show_bu...ield=long_desc
but not work on my site.

Any idea of any setting I need to change or if I need to modify the
show_bug.cgi code?
