Org-mode is git current and otherwise works fine. MathJax is git current and lives in /opt/mathjax/git/MathJax.js. Both firefox 26 and chromium 31 display the MathJax tests perfectly from my org->html test directory. I've copied the example code from the org manual into a file containing: --cut-here----cut-here----cut-here----cut-here----cut-here-- #+HTML_MATHJAX: align:"left" mathml:t path:"/opt/mathjax/git/MathJax.js" #+options: latex:verbatim \begin{equation} x=\sqrt{b} \end{equation} If $a^2=b$ and $ b=2 $, then the solution must be either $$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \]. --cut-here----cut-here----cut-here----cut-here----cut-here-- I exported per the instructions using org-export-to-html. The exported html file has lots of good stuff suggesting that the export seems to be working. But both firefox and chrome display the math bits replaced by [Math Processing Error]. Does anyone have an idea what I am doing wrong? The actual exported is (stuff before elided):

json

\begin{equation} x=\sqrt{b} \end{equation}

If $a^2=b$ and $ b=2 $, then the solution must be either $$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \].

It turns out that removing the "mathml:t" property from the example HTML_MATHJAX line provided in the org-manual section 12.6.8 solves the problem. Hopefully this can save other MathJax noobs the time it took me to wade through ox-html.el and puzzle over the :MMLYES/:MMLNO lines in there. Anyway, I can now complete my transition from generating PDFs to generating HTML and that makes me very happy.

> > [This goes in the Better late than never? drawer...] 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. Nick
