Hi,

I've read all the topics about this error message but nothing works for me.

This message happens on the checkout page after clicking on "add to cart" and filling up customer informations.

Any idea? I struggle with this for more than a month now...

Thks,

Helene

Thank you Jerome,

I've checked this out, the only information I do not have is the Merchant ID.
Do you think this can cause the message error.
And is there any way to "test" the plugin without any ID or with a testing ID?

Thanks,

Helene
