Just checking but you are aware that you have to reach lvl 6 before you can use the rpg shop?

and the bar is all ~coke ~cookie ~beer etc for the commands.

If you are sure you have no problems with the triggers and it's only the shop, then unload and reload it, I'm almost certain that the on load commands have nothing to do with the shop though. I hope that fixes it for you.
If it doesn't, you'd have to show me directly what the problem is.
I'll come to your bot if you give me a server / channel to connect to and see what I can do.
(but tomorrow, it's 2:30am here now)
