When I try to create a portal I get 'An internal error occurred while attempting to preform this command."

Same issue here.
It seems that a Method of WorldEdit 6.0 changed...

As a workaround you can create manually a portal by editing the config and /mv reload ...
but it's not really a nice way and very easy to make issues.

I have the same issue.

I have it too D: please someone help us

Same issue here, apparently World Edit 6 made some changes to their API and MV is not reading it properly anymore...

Spoke to @sk89q and he says Multiverse team needs to update to use the new API within World Edit 6 for this to work.
