Checkout errors: PayPal Europe with PayPal Plus

[Browserwerk]

Hi everyone,

 

we have a shop which is running on prestashop 1.6.1.12. The version of the paypal module is 3.11.4.

Also we're using the PayPal Plus mode.

It seems that the errors only appear with the Plus mode.

 

1. Guest checkout is not working

 

2. Sometimes, more often if the amount is >80€ or there are more products in cart, the PayPal Module shows the following error:

'Sorry at the moment no payments can be processed for technical reasons'

 

Notice for (2):

Could it be a problem with the Tax Calculation which is different in PrestaShop and PayPal?

 

Someone also has these errors or know how to fix them?

 

Best regards
