Spam when hitting blocks

For some reason when ever anyone hits a block I get this message

Code:

I think it is coming from world guard or worldedit
Any help?

 

Its definitely a WorldEdit error. Have you scoured that thread for help on that?

 

It's because you're running a newer version of craftbukkit than worldedit is setup for. Either upgrade WE, or downgrade craft.

They moved some things around and deleted a few files. I had the same trouble with my Ignite plugin and EntityPlayerMP.
