An error occurred when we tried to contact the payment processor. 10401

Hi!

Zen-Cart 1.3.8
I installed paypal express and got this error -->

An error occurred when we tried to 
contact the payment processor. Please try again, 
select an alternate payment method, or contact 
the store owner for assistance. (10401) 10401 
Transaction refused because of an invalid argument. 
See additional error messages for details. 
- Order total is invalid.

I installed paypal ipn. Now, my store redirectet to paypal, but I can see the total price is 0.

I think I got the paypal express error because the price is 0. I don't know.

I hope someone have some tip for me! :)

Thanks

Upgrading to v1.3.9 should resolve your order-total problems.

Thanks for you tip!
I will upgrade later on my test machine.

I find my problem. the problem was a key sensitive crash between a valuta and zone -value.

Is there any quick way to solve this problem without upgrading, I'm still comparing all files in winmerge before doing an update but I'd like to solve the problem as soon as possible.

I am having this same problem .... any one figure it out?

upgraded to 1.3.9h
problem was not fixed... :(

The original post that started this discussion was talking about "the total price is 0". That's what was fixed in 1.3.9.

Your problem, while showing a similar error message, is most likely not from the same root cause. Yours is likely a rounding issue caused by percentage discounts on sales or percentage increases from taxes, etc. Numerous fixes for those kinds of things are included in the v1.5.0beta currently in public review.

I have it fixed ...... all I did was update the paypal and checkout files.
ty though!

Thanks for confirming that you didn't completely upgrade all the files when you did your upgrade.
