Banned when shopping?

[tahbikat]

I'm wondering what would cause a member to be banned when shopping? One of my members was banned while using the shops. I'd like to be able to warn my members not to do whatever action is causing the bans.

Also how do I unban a user from shopping? I put their usergroup back to registered member but they can't shop still.

EDIT: Nvm figured it out!
