Recently I have had problems changing permissions. When ever I added/removed one it would be unchanged. On my server I have PermissionsEx and Vault. When I do /vault-info it says "[Vault] Permission PermissionsEx [PermissionsEx, SuperPerms]" Please note I have checked all servers on my server network, and none of them have SuperPerms installed. Also I have restarted the server and reloaded PermissionsEx many times. Let me know if you need more information!
