I recently updated a course from a 1.9 server (I know. . . hangs head in shame) via upgrade to 2.2 and thence to 2.9. There's a lot of content in a wiki in the course, and most of it seems to have survived intact, but here's the problem:

Every page has the wiki title ("Course Wiki" at the top of the page - and had the wiki description there, too, wasting a lot of space until I just deleted it all.

And whenever I updated a wiki page, the "Recent Activity" block on the course page just shows:

It doesn't show the carefully-crafted page titles which are intended to entice students to read the new material.

Does anyone have any idea what's going on here?
