At <http://en.wikipedia.org/wiki/Square_triangular_number> I just
edited a line of TeX. I saved it and reloaded several times.
That line of TeX is not getting rendered; all I see is the TeX
(I'm assigning this high priority because we cannot afford
to have TeX not functioning; Wikipedia is more successful in
mathematics than in any other field and the rate of editing
those pages is very very high.)
Your TeX was valid and you tried purging the page cache?
