I searched around and didn't seem to find anything about this except one post that talked about clearing my caches (which I did).
My problem is that the admin overlay bar doesn't seem to want to load for my site. There's a bar of empty space for where it would be (if it appeared), but it never does. It did load for a single/couple loads after changing performance issue (such as disabling/enabling aggregation of JS, clearing cache, etc.), but it never lasted. Any help on this baffling error would be appreciated.
