Something is wrong with contents of math table on Wikipedias.
On Polish and French math_html is empty, and math_mathml usually
contains what was supposed to go to math_html but without first
character.
On Polish Wikipedia all new formulas are rendered to PNGs now
because of that.
No such problem on test Wikipedia.
Maybe it's problem with incomplete upgrade ?
Brion: have you replaced binaries in /apache/htdocs*/w/math/ directories
with new versions ?
