Hi Author,
I have been using your plugin since a long time and I find it easy and interesting too, but unfortunately today I am facing some issues with this plugin, I don't know why it's showing such errors. It's showing the error - can't run latex program.
To check this error you may visit my blog page where it's showing the error- http://answernow.in/testing-page/
I request you to have a check on it ASAP. Any help from your side would be appreciated.
Looking forward for your quick response!
Thanks,
Gaurav Taneja.
