I upgraded from 1.3.5 to 1.3.7 last week. I thought everyting was fine, But, when I went to Admin-> Coupon Admin, none of my coupons were displayed.
Instead the following error was displayed above the heading.
Can anyone help out please.
1054 Unknown column 'coupon_zone_restriction' in 'field list'
