HOW I FIX IT

this error is from multiverse

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

There are a few multiverse plugins, which one are you talking about?

 

the core one

BUMP

 

Try to delete the multiverse folder (make sure there is nothing important there, if there is backup it) and start the server again and see if you still get this error.
