If I add <math>A' = \pi</math> to the sandbox, and save (or just preview, as in the link above), and MathJax is enabled in my preferences, I see the following errors on console (Google Chrome 32.0.1700.107): GET https://bits.wikimedia.org/static-1.23wmf13/extensions/Math/modules/MathJax/fonts/HTML-CSS/TeX/woff/MathJax_Greek-BoldItalic.woff 404 (Not Found) GET https://bits.wikimedia.org/static-1.23wmf13/extensions/Math/modules/MathJax/fonts/HTML-CSS/TeX/woff/MathJax_Greek-Bold.woff 404 (Not Found) GET https://bits.wikimedia.org/static-1.23wmf13/extensions/Math/modules/MathJax/fonts/HTML-CSS/TeX/woff/MathJax_WinIE6-Regular.woff 404 (Not Found) I first noticed this error at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)?oldid=595462948
I think Frédéric might know something about that error.
This is a bug specific to Chrome 32. The next MathJax release will include a workaround, see https://github.com/mathjax/MathJax/issues/735. Alternatively, upgrading to Chrome 33 helps as well.
