Solved SkyWars not working...?

Well I start up the server, and I get this hunk of error messages:

Code:

My hunch was that I was running out of memory, but I think my computer has enough left. I also thought it might be the other plugins, but when I tested SkyWars on its own, it generated THIS error message:

What am I missing?

 

Looks like you need WorldEdit

Yayy! It worked thanks! It was bugging me for a while...

 

No problem!
