MaxiGallery installed, clicking "Manage Pictures" does nothing

I’ve installed MaxiGallery 0.5.2 properly (uploaded everything, chmodded "galleries" to 777) but when logged in, clicking the "Manage Pictures" does nothing, fiddling around (submitting an edit with the [[MaxiGallery]] call still intact via QuickEdit on the same page) I’m able to get to the upload page, but this page is pretty unusable (uploading pictures doesn’t work). Any ideas why??

Set the document to be not cacheable or call the snippet using [!MaxiGallery!] and read this: http://www.modxcms.com/document-caching.html
