Thread:Project:Support desk/Fatal exception of type MWException?

After installing Scribunto so I could get templates off Wikipedia with ease, this happens: [fa5327ce] 2014-05-14 13:38:22: Fatal exception of type MWException

I have absolutely no idea what's causing it etc, I've pretty much tried looking at everything. My lua directory is executable and everything is supposed to be like needed, yet this one template is causing me this error (Template:Navbox with collapsible groups) Is it possibly a problem with the template itself? This didn't happen before I installed Scribunto and imported templates from Wikipedia. I have all the modules needed for that template too.

And no, I don't have root access. But the host is running Linux if that's of any help. I'm running Windows.
