I have set an option to use a different local installation of MathJax, and MathJax 1.1 seems to have a different config arrangement.

http://www.mathjax.org/help/configuration/

so I get a MathJax pop up window advising me of this problem with your plugin. I did do a little hacking to get it to work again, but is there any chance you can adapt your plugin to work with MathJax 1.1?

Thanks
