Dear Board,I am trying to customize the html header by editing the header.inc.php in the inc/staff directory.I am adding the following line  <script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>to load a javascript library that allows typesetting mathematical equation in latex.Everything seems to work fine until I want to reedit the equation I just typed. The workflow to reproduce the problem is the following:1. I create a FAQ entry2. I go in HTML mode3. I type the latex equation. Switch off HTML mode, the equation is now wonderfully rendered by some CSS magic4. I switch back to HTML mode to reedit the equation. Now the original Latex commands are gone and in place of them I have the corresponding CSS code. Hence when I switch off again the the HTML mode the rendering now is completely screwed upMy feeling is that the MathJax library is active also in HTML mode and interprets the latex commands translating them into CSS code. This clearly shouldn't happenSo my question is: is there an alternative way to edit the header in order to add a javascript library without having this library active in HTML mode? Or is there any other workaround to this problem.Just to mention that I have been successfully making similar modification to the header of our PhpBB forum and I am not running into any problem.Thanks in advance for your helpAndrea
