I am running a Bukkit server with Spigot 1.7.10 and have run into some issues. Everytime I a low-level player tries to join an SG arena, the error [SG] You do not have permission to join arena 1, comes up. I have given the player rank the permissions sg.arena.join.*, as well as sg.arena.join.1 and so forth. I am using Group Manager. Any help? Thank you.
