Players can not use /money unless they are op. I have added it to my permissions (twice) but they still can not.

This is what I have in my permissions file:
- Craftconomy.money.holdings
- Craftconomy.money.help
- Craftconomy.money.pay
- Craftconomy.money.top
- Craftconomy.bank.create
- Craftconomy.bank.delete
- Craftconomy.bank.add
- Craftconomy.bank.remove
- Craftconomy.bank.deposit
- Craftconomy.bank.withdraw
- Craftconomy.money.holdings

They can use all of them except money.holdings.

Thanks

Try craftconomy.money.balance
