Wiki syntax change?

[Ian MacGregor]

I just visited my wiki profile page:
http://fedoraproject.org/wiki/User:Ardchoille42

I noticed in that table on the right side of the page, the lines
separating the cells are missing. I checked Paul Frields' page just to
see if his was similarly affected and it is. The cell lines were there a
couple of days ago.

Did someone recently make a change that impacts the syntax on the wiki?
