Hi,
I have set-up a wiki at http://wiki.x2592.com and installed (among other things) the MathJax extension (https://www.mediawiki.org/wiki/Extension:MathJax). (I originally tried with the Math extension, but did not manage to get it working, despite the fact that all the prerequisites seem to be met.)
MathJax is displaying Tex-encoded equations OK, but not MathML-encoded equations. The greater-than and less-than characters in MathML tags seem to be being converted to the HTML entities &ls and >.
I'm working with a local git checkout of the MathJax package (although the results were identical using their CDN-delivered version), and a one-week-old git checkout of MediaWiki and the extensions repository. The MW MathJax is the version available as of 7 days ago, too.
The invocation string used to call MathJax is:
http://wiki.x2592.com/MathJax/MathJax.js?config=TeX-AMS-MML_HTMLorMML
Examples of equations and other supported content can be seen on the main page of http://wiki.x2592.com, showing the problem, and the page is currently enabled for editing for anyone that feels like dabbling.
Is anyone able to help me troubleshoot this and get MathML displaying OK?
Many TIA if so, :-)
