Thread:Project:Support desk/How can I teach an extension the function: includeonly?

Hello! I use Mediawiki 1.17 with the extension Improved Access Control.

Now I want to use this Code: Group with a template.

The problem is, the extension don´t understand, which is needed.

How can I teach an extension this function "includeonly" ?

Perhaps with putting a code in a file of the extension? The question is which code in which file?

I love you, if you can help me ;-)
