The main page (http://wiki.code4lib.org/Main_Page) is displaying as 
blank, and the history does not indicate any changes that would cause it 
to be so. In fact, the history for EARLIER changes (eg, my change to 
remove the "new!" text from the link to C4LN) are not displaying 
properly in the diffs.

So, I suspect that something is scrambled.
