This invoice has already been paid

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.4

Hi support team,

I ask for advice. I installed on my Hikashop the Paypal payment plugin. When I try to buy the product, and PayPal gives me an error message:

---

This invoice has already been paid. For more information, please contact the merchant.
At this time, we are unable to process your request. Please return it This email address is being protected from spambots. You need JavaScript enabled to view it. and try Another option.

---

I read on the forums advice on how to proceed ( www.hikashop.com/support/documentation/i...l-error.html#already ).

I set my PayPal account Under "Block Accidental Payments", choose "No, allow multiple payments per invoice ID". I then tried to find in phpMyAdmin jos_hikashop_order. But I found the only jos_hikashop_order but I have not found jos_hikashop_order auto_increment or auto_increment. (see. the image)

Can you please advise me?

I thank you a lot

Pavel

Hi Nicolas,

I progressed according to your advice. When I added ALTER TABLE jos_hikashop_order AUTO_INCREMENT = 10000; and SQL command was successful (scr01) but when I tried to pay a product on my website, and display the same error (scr02)

I do not know what else to set more than: - (((

Many thanks,

Pavel

Hi Nicolas,

I am very very very sorry for take your time. I had the wrong account set up in the PayPal module (missing one letter) .

Now everything is working properly.

I very much appreciate your patience and I wish you much success.

Many thanks,

Pavel
