So I've been trying to get PlotMe to work. I added the permissions with Group Manager so that users in the default group could claim a plot with /plotme claim. However, after they claim a plot, they are unable to place or break blocks on the plot they claimed. I'm the admin of this server, and even I get the message "You do not have permission to build here." when I try to place or break a block on my own plot. Does anyone have a solution to my problem? Your help would greatly be appreciated.
I found the solution to the problem, so I figured I would post it in case anyone else had trouble. All I had to do was remove every Permissions plugin except for Essentials Group Manager. That fixed things right up.
