Warning: Coupon is either invalid, expired or reached its usage limit

Hi,
I am using OC version 3.0.2.0 and default theme and no third party tools. I am facing a problem whenever I try to apply a coupon code an error message says Warning: Coupon is either invalid, expired or reached its usage limit. I want to apply codes to specific products not to all. I have searched the forum and applied all available solutions. For example I have kept the start date one day before the current date and end date one day after the current date and kept the Order Status, Processing Order Status and Copmlete Order Status once to pending and then to processing in settings but to no use. Could somebody please help. I shall be very thankful in any kind response. Please share the link if this problem has already been solved
Regards

Have you also searched the extension store?

Thanks paulfeakins for your kind suggestion.

I have found a solution to my problem by searching through forums. Actually I uninstalled coupons in
admin-->extensions-->extensions-->order totals-->coupons and reinstalled it again and enabled it. That gave me way to my problem. One more thing should be kept in mind that start date of coupon should be one day before the current date and end date should be one day or as many days after the current date. For example today is 6/10/2018. Start date of coupon should be 5/10/2018 and end date should be 8/10/2018. I think this will work fine.
