Atos bug after payment

[PsychoZzzorD]

Hi everybody,

I'm actually testing my Atos payment module with a false card number the bank give me.
When I finish a payment and validate it, it takes me to my website on the order confirmation page as it should.
But after the process it gives me this message :

 

"We noticed a problem with your order. If you think this is an error, you can contact ourcustomer support."

 

After searching some hours on this forum and other sites, and some test inside the Atos module code and in prestashop parameters, it seems like the payment part is doing well.
But the orders get no status in my back office, and are never confirmed.

Does somebody have an idea of how to fix this ?
Thanks in advance =)

P.S. : I'm on prestashop 1.6.1.5 with the Atos module 3.1.3

After a little research, I had find out that the validation variable render "failed1", as if two variables were added together.
