WorldEdit Console Errors - No compatible nms block class found

Hello!

Upon launching the server, I get hundreds of console errors -

24.01 10:12:35 [Server] WARNING [Minecraft.WorldEdit] [WorldEdit] No compatible nms block found.

I've spent an hour roaming forums, wikis, google, (I even ventured in through to page 17 of google). And I have absolutely no idea on the issue nor the solution.
The issue continues, and sends the errors at about 6-12 messages per second.

 

You'll have to wait for the worldedit update.
The changes to the minecraft code have caused the plugin worldedit to function incorrectly.
Which leads to errors.
Also make sure if you have the latest version.

I have the exact same problem on my server and its really annoying, Hopefully the update fixes it

 

The worldedit team fixed it some time back, here:
