Coupon error code

[Henrietta]

I renamed coupon_admin.php to oldcoupon_admin.php and uploaded coupon_admin.php from the original file set. This gave me a new drop down menu in the Gift Certificate/Coupons tab in the dashboard (which had not been there before.)

I then deleted oldcoupon_admin.php

Next I went to the Configuration tab >> GV Coupons and put the number 20 in both Maximum Discount Coupons per page and Maximum Discount Coupon Report Results per page.

This removed the error message.

I do not know which of my actions removed the error code.

If you set the Maximums to 20 and they were 0, that is part of the problem ...

Reloading the file: coupon_admin.php could have corrected other issues ...

Hello,

Using:
Zen Cart 1.3.8a
Patch: 1::

Had the exact error message as original poster.

I applied the second part of the original poster's solution:
"Next I went to the Configuration tab >> GV Coupons and put the number 20 in both Maximum Discount Coupons per page and Maximum Discount Coupon Report Results per page."

And this solved the problem for me.

Thanks!
