I try to install MathJax on my offline dokuwiki-server so that the MathJax-plugin does not try to connect to the internet (initial problem here: https://forum.dokuwiki.org/d/18234-local-offline-dokuwiki/2).
I downloaded the following archive (
http://docs.mathjax.org/en/v2.7-latest/installation.html#obtaining-mathjax-via-an-archive) and copied it to the RPi via scp. Extracted the zip and moved the directory MathJax-2.7.7 to /var/www/dokuwiki/lib/plugins. Then set the permission again with sudo chown -R www-data:www-data /var/www/dokuwiki
In the default.php of the MathJax-plugin I changed the line $conf['url'] = 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.4/MathJax.js?config=TeX-AMS_CHTML.js';
to $conf['src'] = '/var/www/dokuwiki/lib/plugins/MathJax-2.7.7/MathJax.js?config=TeX-AMS_CHTML.js';
Then I rebooted the RPi. When I now try to write Latex-code (e.g $a2+b2=c2$) it shows no pretty formulas :-(
Do I need to change some other settings?
