I had problem with OPC Rupostel:
1) I have installed the latest version of VM from virtuemart.net
2) Problem doesn't appear in OPC v. 2.0.3193) Problem is even in latest OPC ver. 2.0328.
I add normal coupon and it seems to be all right (Discount Coupon successfully added) but the problem appears just after "purchase confirmation": Error x (coupon code): Coupon code not found. Please try again.
Finally the coupon value is discounted but at the invoice I can't find any coupon code it's hard to say what coupon was calculated. (As I said it happens only in ver upper than 2.0.319).
I have received answer form Rupostel:
Re: Problem with Awo Coupon
Postby admin » Thu Jan 12, 2017 2:12 pm
hello, i am testing latest awo+opc+vm and i found that awo is not capable of using shipping coupons before the shipping is selected and for this reason i suggest a solution:
OPC config -> Display tab -> DO NOT use ajax for coupons
make sure this is NOT CHECKED (I.E. it's enabled)
VM deletes the coupon automatically upon coupon validation and thus the coupon is not used.
best regards, stan
