withMathJax not working anymore

[Christian S]

Hi guys, thanks for your awesome work. I just want to point out that withMathJax() is not working anymore, not just in my own app but here aswell:

http://shiny.rstudio.com/gallery/mathjax.html

Any idea when this will be fixed? Any work around, when using shinyapps for example?

Its an issue with the MathJax secure CDN http://hugo.spf13.com/tutorials/mathjax . If you browse to https://c328740.ssl.cf1.rackcdn.com/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML you will see it is currently not delivering content. Essentially the old secure CDN has been retired https://groups.google.com/forum/#!topic/mathjax-dev/i-NBOzeD7TU and relevant links/functions need to be updated.

Looks like its fixed in the Shiny dev version https://github.com/rstudio/shiny/issues/573

You are absolutely correct. I just upgraded shiny there and
re-deployed the app. Thanks!

devtools::install_github(c('rstudio/htmltools', 'rstudio/shiny'))
