Hmm. I wish I could figure out how to work some of these cases into the docs, but the problem is there's no consistency or sense to it. Stuff seems to be different on every server. I really don't know what the problem with their software is, but it seems unable to maintain its own configuration with the GUI safely.

What exactly led you to that change? I wouldn't even know what that has to do with it. Does that just act as the shell to run every filter installed?
