Need help with Redbeard's Booty quest

I've gotten all three map pieces and Redbeard's treasure map, but the portal at the back of the island doesn't do anything at all. Does anyone know what's going on?

 

Try going back to the island selection area and then try if the portal works again. If that doesnt work, try relogging. If that doesnt work, redo the last parts of the quest and check your content book if youre actually at the right quest stage. If youre ever stuck try /class or worst case /kill.
