This works fine for me if I delete the path spec in your HTML_MATHJAX
line, so my guess would be that there's some problem with your local
mathjax setup. Are you sure that your other tests use your local setup?
Maybe they go offsite?
BTW, with mathjax providing a proper CDN, is there any point of having a
local setup[fn:1] or even the default setup at orgmode.org? Maybe the
out-of-the-box default in org should be "let the mathjax CDN handle it."
Footnotes:
[fn:1] ... assuming that you want to *use* mathjax, not hack it.
