This manual is built up for phpBB-3. You can download the current version (on 05.11.2016 it was phpBB-3.1.10) and install it on your local system. We used a XAMPP installation with Apache Server and MySQL Enviroment.
Get MathJax (download or CDN)Go the official MathJax-site and obtain MathJax. You can either download the library to your local system or use their Content Delivery Network (CDN). In this example we use the CDN, which must be included in specific files of your phpBB installation. In this example we implement MathJax in the overall header of the phpBB installation.
Integrate MathJax CDN into phpBBCopy the following code line and insert it into the overall_header.html of your phpBB installation. In my example the html-file is located in folder styles/prosilver/template.I added the CDN link right before the header of overall_header.html ends.copy
We would be happy to support you integrating LaTeX4technics into your website. Feel free to write us on social media or mail.
