Thread:Project:Support desk/Hiding of language selector possible ?

How can I hide the language selector on each page with MediaWiki 1.17.0 ?

For others: I already found this similar threads:

$wgHiddenPrefs[] = 'language';
 * hiding selector in preferences of the user

on reference Manual:$wgLanguageCode


 * disabling unused languages (a german thread)

on reference Manual:$wgLanguageCode/de

But that's not what I mean. My local Wiki needs no language selector. How can I get rid of it.

Thank you for answering ...
