I'm having trouble editing my configuration files. I've read the developers manuals and am following their directions. For example --

I set ConfigItem CustomerPreferencesGroups###Language to Valid="0"

Yet the box still displays on my customers' preference page.

I removed the ConfigItem completely, also to no avail.

Yet these are the only files in the entire OTRS system, including the DB, that seem to have the words "frontend language" in them.

Am I missing something completely? Like, do I need to be changing these config options from a perl prompt?

Any help is appreciated!
