+I installed mathjax via the pandoc-iki plugin as described [here](http://stackoverflow.com/a/8444409/406686)
+
+The rebuild of an old site containing math is missing the following lines:
+
+
+ <script src="/mathjax/MathJax.js?config=TeX-AMS_HTML-full" type="text/javascript"></script>
+ </head>
+ <body>
+ <noscript>
+ <div style="color:#CC0000; text-align:center">
+ <b>Warning: <a href="http://www.mathjax.org/">MathJax</a>
+ requires JavaScript to process the mathematics on this page.<br>
+ If your browser supports JavaScript, be sure it is enabled.</b>
+ </div>
+ <hr>
+ </noscript>
+
+----------------------
+
+I finally noticed that the `page.tmpl` was messed up. It seams that the upgrade deleted the relevant `mathjax` line. Adding this makes it work again. [[Thanks|done]]!
