Coupon code not find

Hello. I added a new coupon with your component (Awocoupon PRO), so when i go to the cart and apply this code - that writes "Coupon code not found", but the code is counted. When i confirm the order - the total price is without the coupon sale. What could be the problem?

Please send me some instructions for integration of AWOcoupon to One Page Checkout.
Joomla 3.6, VM 3.0.16

Hello,

Does it work without one page checkout? If so, then please contact the developer of the one page checkout. If using rupostel one page checkout, trying turning of ajax coupon processing to see if it resolves the issue.

Configured and now coupons are working properly. The problem is occurs when creating coupon choose the payment method. In the basket of an error: the coupon code is not found. Please try again.
Please tell me how to solve the problem.
Thank you

Hello,

Just so I understand the problem: the coupon code works fine, but when you select payment method in the coupon it does not? This might be due to using one page checkout, since the payment method is directly chosen on the page and no way for the coupon to register it has been chosen.

Is the coupon processed through ajax? If so, maybe disabling that would fix the problem?

Yes, the coupon is processed through ajax. Do you know where i can disable the coupon ajax processing?

Hello,

Is this Rupostel one page checkout? If so in the component, go to the 'Display' tab, and make sure 'DO NOT use ajax for coupons' is checked.

Hello, yes, i'm using Rupostel OPC. Disabled ajax, but it's not working, just updating the page.

Hello,

I have been testing this with the latest Rupostel OPC and it works. first you would need to use ajax coupon code. So make sure you uncheck the box 'Do not use ajax for coupons'. Then in the front end, enter the coupon code. It should show as accepted in the cart. If you change the payment method to a valid payment method, it will show a discount and if change it to an invalid payment method, the coupon row still show but the discount will display as 0. Are you using the latest version of opc?
