@Mohammad - the plugin has been tested many times with different settings and it's working without any problems. If it "didn't enter", then you should check the logs for errors. It would also be nice to explain how you installed the plugin, because this one is a little more complicated.
@MihailoZ - what do you mean by "shop info"? You can use the command "/points" to check how many points you have. They also show up in the shop itself and you can even make it display them on HUD - see the settings.
