OK thanks.

No, I don't remember doing that. Is there a way to change it back. And will my server start once I do?

This is what I saw on my latest logs

I had just recently closed the server and when I went back to start it again, It wouldn't. It would appear as offline, then I clicked start and after a minute or two it still said offline. I also tried force hibernating and repairing the core files, but it still will not start. I don't know what is wrong. Can someone pls help?
