LaTeX rendering problem in a local installation of the sage notebook server

[Keir Lockridge]

Hi,

I have Sage v6.2 installed 'in the cloud' (Amazon). The OS is RHEL. I have used Sage for a couple of years without incident, but I am suddenly having a problem with LaTeX rendering in the notebook. When I enclose a formula in double dollar signs, it renders just fine as a centered equation. When I enclose a formula in single dollar signs, it does nothing (it just appears as plain text; see attached screenshot). I didn't have this problem with v6.0, but I am sorry to say I can't swear that's the only change that I've made to the server.

The server has a working local installation of MathJax. LaTeX functionality in the locally installed wikis works fine.

Anyone have advice for diagnosing the problem?

Thanks in advance --

Keir

Latex in the notebook shouldn't be broken. It was completely broken for 6.1 but was fixed in 6.1.1. There has been no (released) upgrades of the notebook since then. I just checked and inline equations work fine here in 6.1.1 and 6.3.beta3. Sorry, I don't have 6.2 to test.

I was finally quick enough to highlight and copy the MathJax error:

File failed to load: https://sage.xxxxx.org/javascript/mathjax/config/../../dynamic/mathjax_sage.js

But, I am having trouble actually finding this file.  When I load the URL in my browser, I get a blank page ('view source' leads to an empty document) and not an error.

Is your sagenb installation complete? This file is present and
distributed with the notebook:
https://github.com/sagemath/sagenb/blob/master/sagenb/data/sage/js/mathjax_sage.js

I downloaded and complied the sources tarball for 6.0 and had been using sage -upgrade since then.

I found these files in the sage directory tree (where the 'sage' executable is), and both are non-empty:

./local/lib/python2.7/site-packages/sagenb-0.10.7.2-py2.7.egg/sagenb/data/sage/js/mathjax_sage.js

./local/lib/python2.7/site-packages/sagenb-0.10.8.2-py2.7.egg/sagenb/data/sage/js/mathjax_sage.js

Thanks for your help, by the way. I'm currently compiling 6.1.1 just to see if a that might solve the problem, but it's still working.

UPDATE:

I switched to 6.1.1 and the problem went away.
