When marking and creating portals, this call always failed since it was changed in WE6 (and WE5 is not functional in spigot 1.8 - leaving us hanging):

Caused by: java.lang.NoSuchMethodError: com.sk89q.worldedit.LocalSession.getSelectionWorld()Lcom/sk89q/worldedit/LocalWorld;

I know its not your fault, but not sure they're re-adding legacy support for the selections.

Thanks

I have the same issue I was able to create a portal manually. Since I'm running Worldedit 6.0 and have to run it for other plugins, I just copied and pasted a portal in the portals.yml file and edited with correct cords and changed portal name and destination worked great.

+1 for this fix. Adding portals manually is a pain!

yes it is a pain, I have not been able to figure out how to manually configure a new portal.yml file. Been working on running the newest Spigot and decided to do fresh install of all plugins to see if that will clear up the issues I'm having. Well I'm not able to create a portal so I will not be able to see. I even tried to use the portla.yml file from running server, will not let portals run.
