Hi Vishnu,

Does any other, simpler, equation render on your site? The equation listed in your debug results works just fine on my 1.9.19+, 2.34+, 2.4.1+, and 2.5 Beta sites, which are all on a Centos Linux server.

\Large f(x)=\int_{-\infty}^x~e^{-t^2}dt gives a render of $$\Large f(x)=\int_{-\infty}^x~e^{-t^2}dt$$

It also seems to work fine here on Moodle.

no, not even a simple equations. I know its a problem with the online server because i render the equation in local wamp server, but not able to render in server. I couldn't understand what configurations to be modified in the server.

If the basic plugins have not been activated then there will be nothing. Need Algebra Notation and Tex plugins at least. These can be activated via the Plugins > Plugins Overview. If you go to something like TexLive, which I think has TeXWorks as native, you can use Tex in any HTML document and create your own PDFs as well. If you are using a Windows machine and do not have access to the server, you can download and install MikTeX, with is a useful tool, for your local machine. Create the TeX in a PDF format and upload it. I would agree it is easier and simpler having it in Moodle., but sometimes Admins are not co-operative if they do not know something.

This a library problem that really doesnt have to do with moodle. Work your way though to the bottom of this thread. https://moodle.org/mod/forum/discuss.php?d=79388

mimetex is a fallback. Really better to use texlive or mathjax

Thanks

In case it helps anyone else we flxed our problem by disabling the TeX filter. We think their may have been some kind of conflict with MathJax 2 which we had recently added.
