Thread:Project:Support desk/Changes to sidebar don't show up

I've just installed Mediawiki version 1.22.0 with no changes other than configuration. I've edited the MediaWiki:Sidebar but the side bar on my site doesn't really look like what I'm editing and my changes have no effect. If I refresh and clear cache, I see briefly what might be the same as what I'm editing, but it gets covered up immediately by something else. Site is http://windangel.org. I've read the documentation for MediaWiki:Sidebar, didn't understand some of the more esoteric discussions and have no idea what "skin" I might be running. This may be way more complicated an app than I need, if changing the sidebar is this difficult. I may have to look elsewhere.

Thanks, Jim.
