I can't see any attached files, there has been trouble with this before but I don't know what caused it.
If you made the static wiki by rendering the page view template as static html then the result isn't interactive. I don't think it contains any javascript so none of the interactive components work.
That is what happens if you used the render command for the tiddler
$:/core/ui/PageTemplate or something like that.
If that isn't what you did, my first guess about your problem is that one of the settings for the story river width are set too wide and an invisible part of it is covering the sidebar.
This can also happen with page templates and anything that is set to display on top of everything else. I don't know of anything related to the host that would cause the trouble you are having. When something like that happens to me it is because I have some setting in my local version that I excluded from the exported site. Unfortunately the only way to figure out what the problem is in this case is to poke around until you find something out of place. If you have the wiki up somewhere publicly accessible we can try and look at it to help find a problem.
