The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

This seems to be triggered by the wgUseCategoryBrowser mode, which was mysteriously enabled on test.wikipedia.org. (I've now disabled it, so the sample URL no longer triggers the error.)
There's a good chance there's other breakage with this mode, which is off by default and unused at Wikimedia sites.
WORKSFORME as of current trunk. All elements are nested properly.
