Some players may not use teleport due to this message.
"you may not teleport in this area"
although they are not located in blocking areas or cupboards
How to fix it?

I also have a player on my server getting the same message but is able to use /tp and /tpb.  So far it's only one player so I am not sure why.

It's odd though cause it's only some players, not all.

@rfc1920 Hey i am also having this issue but it is when a player is attempting to use /home add "name". is there any reason for this?

@rfc1920
I have two users having an issue where they cannot set a home or use any tpr functionality. I have searched through the data and removing permissions makes it so they do not see any error. but once they are giving permissions all they see is you may not teleport in this area. Any ideas?

im also getting nteleport your target is currently not available when trying to tpr to him. @rfc1920

They did but i had recently changed my chat groups for new users. it was reset to default :) thats why. Thanks @EyrUnCom

"You may not teleport in this area" does come from ZoneManager afaict.  We do a call to a hook called CanTeleport, and a few plugins use this.  On my server, it's only ZoneManager, Quests, and Vanish.  YMMV.
