Math: MathJax processes strong.error elements, but those are not exclusive to MathJax (also generated by Cite and Scribunto)
Closed, ResolvedPublic

Description

The error message « Des balises <ref> existent, mais aucune balise <references/> n’a été trouvée. » is parsed by MathJax when I go to [[fr:Spécial:Redirect/revision/97444940]].

PS: in debug mode, I have 6 lines in console : "MWDeprecationWarning: Use of "sajax_init_object" property is deprecated. Sajax is deprecated, use jQuery.ajax or mediawiki.api instead."

<references/> n’a été trouvée. » is parsed by MathJax when I go to
[[fr:Spécial:Redirect/revision/97444940]].

Why do you think that this is "parsed by MathJax"?

The problem seems to happen because of this line:

dont la valeur s'élève à plusieurs ''milliards'' USD<ref>http://blogs.smithsonianmag.com/smartnews/2013/10/how-much-is-wikipedia-worth/</ref>

as the author did not add a line

<references />

at the end of his/her comment, hence there is no place where to list that ref.
Hence MediaWiki puts a warning at the end of the page.
Adding the missing line should fix it, I assume.

I don't see a valid bug here but instead expected behavior, but maybe I miss something?

I don't see the error myself but from the screenshot it looks like MathJax's \ref command is somehow activated, see http://docs.mathjax.org/en/latest/tex.html#automatic-equation-numbering.

IIRC the Math extension restricts MathJax rendering to elements of a certain class so perhaps something is mixed up there. Alternatively, the Math extension could deactivate that command completely (I don't think it's used).

Have you enabled MathJax on frwiki?

  • Bug 55888 has been marked as a duplicate of this bug. ***

I've confirmed this on English Wikipedia. From duplicate bug 55888:

After I added a reference using VisuaEditor[1] I noticed there was no
<references /> tag in the page, and consequently there was the usual cite error
which says "Cite error: There are <ref> tags on this page, but the references
will not show without a {{reflist}} template (see the help page)."

The problem is: this message was displayed as if it were a formula, when I was
using MathJax.

The message is normal if I'm logged out (since the default is PNG images
instead of MathJax)

In that way we'll never make progress!
