Hello
I’m trying to bring the power of latex to modxcms
it worked fine with the mimetex plugin
but now i’ve been working with that for a log time
and would like to move on to real latex with
the latexrender program
http://www.mayer.dial.pipex.com/tex.htm
works with phpBB and others.
All i need is a plugin similar to mimetex
After several hours of writing phpcode which I don’t understand
I will ask in this forum.
as anyone can see i have used the fantastic plugin from Luca Allulli and Daniele Calsisi
(thanx for the great work.) to start out with
but it does not at all work
so maybe someone can help me?
at the moment i run the website on a local copy on 192.168.1.4
scincerily
Christoph
