[Done v1.5.4] You must spend at least US$0.00 to redeem this coupon

[sadie]

What happens if you edit the file:
/includes/modules/order_totals/ot_coupon.php

and change the line around 190 to include the code in RED:

        if ($coupon_result->fields['coupon_minimum_order'] > 0 && strval($order_total['orderTotal']) < $coupon_result->fields['coupon_minimum_order']) {

Does this correct the problem for you?

Yes, that worked! Thank you.

By coincidence, I just noticed this happening on my site too. The supplied patch corrects the problem. Thanks!
