Thread:Project:Support desk/Templates are not working in Mediawiki:Sidebar utill V1.18

In Versions 1.15 - 1.17 I could easily include Templates to the Mediawiki:Sidebar. This is obviously not working any longer in 1.18. Including a Template to it the page Mediawiki:Sidebar is show corrrect but the template is not shown in the sidebar itself. I used this in combination with the extension MyVariables Extension:MyVariables esp. The template. So I could include user specific menue to the Sidebar very easily. Using Template call on Mediawiki:Sidebar and a Template for each user in User:NAMEOFUSER/Sidebar. So what has changed to this?
