This happens for me for all documentation (whereever there is a formula
like `f(x)=y`). I am using Firefox, MacOS 10.6.8.
Travis is using Windows, so he would need to be more specific (as I
do not know).

This happens for all TeX code though. Do I need to install something?

Could you please give one concrete URL, relative to SAGE_ROOT?
I just opened Firefox, start browsing documentation, cannot see any problems...

You need to be online. Mathjax is uploading fonts on the fly.

 Both Travis and I are having trouble viewing the documentation after

 sage -docbuild reference html

 It yields a lot of [MathError] when viewing the html sources.
 The problem started occurring some time between 5.4.beta1 to 5.5.rc0,
 most likely due to the switch to mathjax from jsmath.
 Does anyone else have this problem? What do we need to do to fix this?

When I review a patch and want to check its documentation I do

sage -b
sage -docbuild reference html
.
Build finished.  The built documents can be found in 
/Applications/sage-5.5.rc0/devel/sage/doc/output/html/en/reference

Then if I check on my local computer in Firefox under for example

file:///Applications/sage-5.5.rc0/devel/sage/doc/output/html/en/reference/sage/combinat/posets/posets.html

the fourth line is

Constructs a (finite) [Math Processing Error]-element poset from a set of 
elements and a directed acyclic graph or poset.

But this happens in *all* files. This is not specific to a particular
doc.

I am online.

 Hi Anne,

 I reviewed that ticket, and I didn't see anything like this.

 Could you please specify the particular URL in documentation where this
 can be seen?
 As well as your browser/OS...

OK,  I can confirm this. It is Firefox-specific, as on OSX 10.6.8 I
only see this on Firefox (5.0.1), but not on Safari and Chrome.

Here are errors (from Firefox error console):

Error: no element found
Source File: chrome://web2pdfextension/content/feat_support_new.xul
Line: 1, Column: 20
Source Code:


Error: c.FONTDATA.FONTS.MathJax_Main[8212][5] is undefined
Source File: 
file:///usr/local/src/sage/sage-5.5.rc0/devel/sage/doc/output/html/en/reference/_static/jax/output/HTML-CSS/imageFonts.js
Line: 15

no idea why this fails on Firefox, but works on the remaining
browsers. Perhaps mathjax  (or/and Sage?) treats Firefox in a special
way.

Works for me on Firefox 17.0.1 on Linux x86_64. Can somebody try and see if 
its fixed in more recent recent release?

In more detail: go to  and follow the 
link for "Current Version: MathJax-2.1". Unzip the file to get a directory 
called something like "~/Downloads/mathjax-MathJax-24a378e". Now, go to 
SAGE_ROOT/devel/sagenb/sagenb/data and do

$ mv mathjax mathjax-old
$ mv ~/Downloads/mathjax-MathJax-24a378e mathjax

and try looking at the documentation.

Or perhaps Volker meant a more recent release of Firefox. What is the most 
recent release available for OS X 10.6.8?

Thats what I meant - most recent version is 17.0.1 on all platforms.

I should mention that this kind of error was reported on
http://trac.sagemath.org/sage_trac/ticket/13143
but nobody was able to say exactly where the problem lies.
Now we know, it's Firefox-specific.

I can also add that on OSX 10.5 with Firefox version 3.6.28 the situation is
the same.

Anyhow, the workaround ---use another browser--- is there...

Dima

I just upgraded to 17.0.1. That did not seem to help.

I switched to Chromium (18.0.1025.168) and then it worked for me, so I can 
reconfirm it is a Firefox-specific issue. I'm running Firefox 15.0.1 on an 
Ubuntu 10.04 VM through VirtualBox.

This is the following issue:

http://docs.mathjax.org/en/v1.1-latest/installation.html#firefox-and-local-fonts

I do have stix fonts installed in the OS (Fedora 18) and equations render 
fine. If I uninstall stix-fonts then I get the [Math Processing Error]. 
Apparently they are only included from OS X 10.7 onward. 

At http://www.mathjax.org/help/fonts/ there are detailed instructions for 
how to install stix fonts manually.
