typesetting problem in documentation

[Martin R]

I just checked out develop and built it, without any trouble, EXCEPT, that the documentation isn't typeset properly.

I am using Firefox 37.0.1 on kubuntu 14.04.

I do not have this problem with sage 6.5 on this machine.

Mathjax (I think) briefly displays a warning, which ends with

File failed to load: file://..._static/FONTS/HTML-CSS/TeX/png/imagedata.js

(very hard to see, because it disappears again...)

The LaTeX is output verbatim, that is, there are not the usual red error boxes.  Also, hovering over it, the mathjax configuration box does not appear.  For example, in

file:///home/martin/sage-develop/src/doc/output/html/en/reference/algebras/sage/algebras/weyl_algebra.html

I see:

    Let \(R\) be a commutative ring. The (differential) Weyl algebra \(W\) is the algebra generated by \(x_1, x_2, \ldots x_n, \partial_{x_1}, \partial_{x_2}, \ldots, \partial_{x_n}\) subject to the relations: \([x_i, x_j] = 0\), \([\partial_{x_i}, \partial_{x_j}] = 0\), and \(\partial_{x_i} x_j = x_j \partial_{x_i} + \delta_{ij}\). Therefore \(\partial_{x_i}\) is acting as the partial differential operator on \(x_i\).

Help!  I cannot review tickets!

Works for me on sage-6.7.beta2 and firefox 37.0.1

I do get an error in the console: downloadable font: download failed (font-family: "MathJax_Blank" style:normal weight:normal stretch:normal src index:0): status=2147500037 source: about:blank in the console, but math still displays for me. Possibly a font substitution issue?

We don't include the image fonts since they are huge and all modern browsers support real fonts. 

We did upgrade mathjax recently. There is no hover menu, you need to right-click.

Right-clicking shows no special menu.  Looking at the html source, I see:

<p>Let <span class="math">\(R\)</span> be a commutative ring. The (differential) Weyl algebra <span class="math">\(W\)</span> is
the algebra generated by <span class="math">\(x_1, x_2, \ldots x_n, \partial_{x_1},
\partial_{x_2}, \ldots, \partial_{x_n}\)</span> subject to the relations:

I guess that's alright.  In firefox' web-console I see:

TypeError: d[0] is undefined MathJax.js:19:46419
TypeError: c.FONTDATA.FONTS.MathJax_Main[8212][5] is undefined

Is that an upgrade from earlier sage versions? Upgrade to ensure that the re is no old mathjax lying around.

sage -f mathjax

make doc-clean

make doc

no.  all completely fresh.  However, there is a sage (my production sage :-) in the path, might that be a problem?

Thanks,

Shouldn't be a problem, though maybe you can try without and report back...

[Martin R]

Indeed, no change.

I installed konqueror, where things work.  So it is a firefox problem...

[Martin R]

Let me summarize:

firefox with sage 6.5 is OK
firefox with sage develop is not OK
konqueror is OK with both.

A miracle: I checked out ticket #17760, rebuild, now it works also in firefox.
