[SOLVED] PayPal express checkout vmError: Unexpected ACK type

[titolin10]

Hello everyone,

Back again with this issue that I found when I activated Paypal express checkout.

When I click on view cart or I navigate from menu link to cart I get the error.

The same when I try to click on the "Check Out Now" button.

Your help is highly appreciated.

Incorrect credentials for PayPal express ?

Jörgen @ Kreativ Fotografi

[titolin10]

I used my default sandbox business account to test with certificate that I downloaded from one of the paypal pages and immediately I uploaded the certificate to the safe path in VirtueMart and selected it from the payment configuration page. (I hope I didn't miss anything else to install the certificate).

[titolin10]

**Update

Just right now the issue solved after rechecking the credentials again (Thanks Jörgen)

For reference for other people who may search for the same error message:

When you use PayPal sandbox don't use account name as a user name (This was my mistake)

The sandbox account name is like an email address - don't use it as a username in payment configuration. instead, use the username with the password that you'll get in the "API Credentials" tab.

I don't know how I did it wrong maybe I was sleepy hahaha!

Thanks for the help Jörgen

Nice to hear that it has worked out for You
