Issue with 'User group after purchase'

Hi,

Before solving the issue we need to understand it.
I tried on my end but I'm not able to reproduce the problem.
The value of that setting is really empty in the database when I try to do the same, and I don't get the warning.
So this indicates that there must be a value on your end stored in the database for the "user group after purchase" setting.
Could you go in your PHPMyAdmin, open the hikashop_product table, search for that gift card product entry (with the product_name for example), and look at the column "product_group_after_purchase" ?
There should not be a value for it.
Could you tell us what you have there ?

Hi,

Now the question is how these "none" were added there ?
Did you import the data and it was written "none" in that column for these variants instead of having an empty value ?
Was is NONE in uppercase that you saw in the database ?

Hi,

Thanks for the details.
We'll replace the line (2 places):

if(!empty($product->product_group_after_purchase) && $product->product_group_after_purchase != 'all' && $product->product_group_after_purchase != '') {

if(!empty($element->product_group_after_purchase) && !in_array($element->product_group_after_purchase, array('all', '', 'none', 'NONE'))) {
