I'm trying to change the sidebar in my one-click easy install MediaWiki. When I first went to MediaWiki:Sidebar, I saw what I guess is a default version, because I couldn't edit the page. I could create it, and did. But the changes don't seem to take effect - period. I just see the default (which seems to vary as I wander around - at least, the contents of the Toolbox change).
I'm confused, and the MediaWiki help doesn't really help.
