Paying Affiliates

I am trying to pay an Affiliate, but there are two issues, one serious.

First - is there a way to pay all unpaid amounts at once or can you only pay one affiliate order at a time? I'm using PayPal for all transactions. (See 1st screenshot.)

Second - when I click on the coin icon to pay an Affiliate for a single order, I get an error - see 2nd screenshot. Even though I get the error and cannot be redirected to PayPal to complete payment, I receive a "New Order Created" email saying I have paid this affiliate.

Please advise soon - I need to pay my affiliates asap and need to know how to resolve the error.

Thanks!

Thank you for the quick reply. I checked the user.php file you referenced, and already had that line of code under function_costruct. My current version of HikaShop is 2.0.0 but I will have to pay in order to upgrade to the newest version. Is there any other temporary fix that you know of until I am able to upgrade?

Many, many thanks! That fixed it. I was missing the last pay_process line.

A new Affiliate question: I had three orders that required an Affiliate payment. I have now successfully sent a PayPal payment for the first order in the que, but now I cannot figure out how to pay the next order, since nothing is appearing in the "Total Unpaid" field (see screenshot). It shows I owe money but does not provide me a way to submit a payment, i.e. the little coin icon is grayed out/disabled, and the list of orders to the right is empty. If I go to the Orders menu, I can see a list of orders that still require payment, but for some reason this list doesn't also appear Affiliates>Partners section.

Thoughts?

Thank you so much for your assistance, Nicolas. Happy to report all of your fixes have worked and we are back in business!
