Voucher Codes Show Errors But Works

I have today tried to set up a new Cart Promotion, but I get both the following orange error

Warning : The entered code cannot be applied, because it does not meet the requirements.

and the following Green warning box

Notice : Applied promotions: Virtual Tea Tasting

Discounts are added to cart though, but would be worrying for a customer to see both.

Any one got any ideas of what this could be ?

Thanks for any help in advance



I'm having the same problem. The warning doesn't happens when I sign out. Only when customers signed in... will it display the error.
