Description:
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
code itself.

(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.)
