With Mediawiki on sourceforge.net I try to use MathJax 2.2. After installation on the VPS, the MathJax test is working (http://freeplane-up.sourceforge.net/wiki/MathJax/test/index.html). But the MathJax does not recognize by mediawiki. After setting up LocalSettings.php as example (https://www.mediawiki.org/wiki/Extension:Math) I have an error when mediawiki try to render TEX code. on Apache : PHP Notice: Use of undefined constant MW_MATH_MATHJAX - assumed ' MW_MATH_MATHJAX' in /home/project-web/freeplane-up/htdocs/wiki/LocalSettings.php on line 309, referer: http://freeplane- up.sourceforge.net/wiki/index.php/LaTeX_in_Freeplane tail of LocalSettings : $wgUseMathJax = true; // enabeling MathJax as rendering option $wgDefaultUserOptions['math'] = MW_MATH_MATHJAX; // setting MathJax as default rendering option (optional) $wgMathJaxUrl = 'http://freeplane-up.sourceforge.net/wiki/MathJax/MathJax.js?config=TeX-AMS_HTML'; // specifying the path to local MathJax in case MathJax's CDN should not be used (optional) ?> When I do a "grep -i MW_MATH_MATHJAX ..." on wiki and MathJax package this constant is not define other than LocalSettings.php !
Based on http://freeplane-up.sourceforge.net/wiki/index.php/Special:Version and your paste above, you don't have the math extension included. You need to add the following before the maths settings you already have: require_once("$IP/extensions/Math/Math.php");

It was part of MediaWiki core, but it no longer is. In later versions, you need to install the extension, as noted at https://www.mediawiki.org/wiki/Extension:Math (see Download and Installation sections). This is not a bug in the software. If you need help installing the Math extension, try emailing mediawiki-l (https://lists.wikimedia.org/mailman/listinfo/mediawiki-l).
Finally texvc can not be compiled in Sourceforge to activate normally Math extension. See "http://www.mediawiki.org/wiki/Manual_talk:Installing_MediaWiki_on_SourceForge.net#Enabling_math_under_Sourceforge.net". So I close this ticket. Regards for your help.
You shouldn't need to compile texvc if you're only using MathJax. That is a very old post from before MathJax was even available. I wouldn't be surprised if the SourceForge shell options have changed too. There is also a Debian/Ubuntu package for texvc, mediawiki-math.
