I often start out my posts like this, but I'm sure we're doing something wrong. We have a basic neighborhood server. For a while, it was just the spigot server with WorldEdit, WorldGuard, TreasureChest, and PEX. I was able to do all the things I needed until I couldn't. Today, I added Essentials. Now, for some reason, everything is screwy. For example, when I used to type "/help (number)" I would get any of 22 pages of commands definitions. Now, nothing appears. When I used to type "/setwarp" it told me "command unknown" because I hadn't installed Essentials yet. Now, with Essentials installed, it says nothing but also does nothing. That's as far as I got in figuring out what the problem is because, honestly, I don't want to break anything. Any thoughts? I am happy to upload any files you would like to see that might help solve the problem.
