was the problem.
When I disabled that product the source code came back up.

I would like to run both together. Any ideas?

I'd have to take a deeper into that mod and see why interacts with vlatex to find out what causes the problem. But I won't be able to do so until next Wednesday, I'll be out of town, I'm very sorry.

In the while, you can try to contact Bills, see if he can help you. Or you can try to paste the code directly into the headinclude template

  var vlatex_popup_close = 'Close';
