I had my site running fine with MJ for several weeks, and then all of a sudden, it stopped working. The component wasn't serving up mobile templates.

So, I completely uninstalled MJ, then reinstalled 0.9.12. It still wouldn't work. So, I uninstalled everything, reinstalled 0.9.9, and it worked! So, I tried upgrading to 0.9.12, and that worked, too. But, if I try and install 0.9.12 first, it doesn't work.

This seems like a major bug....
