Hi There, from what i can understand you can use paypal express to handle payments in the cart as long as there is no subscription (recurring payments) in a product, if thats the case you get the error there is a problem with your sellers email address.
I contacted paypal merchant support and was told this.
We tested your cart and if a user selects a product that doesnt use a subscription then the process completes as expected. However, if there is a recurring payment then the gateway plugin redirects it through the paypal standard gateway which you dont have hence the email error.
Now my situation is this, i have the one fully verified business account set to use paypal express which a few other plugins rely on.
I cant switch to paypal standard or the others will break, so how can i get whmcs to use paypal express when.
a)paying for a product with recurring payments in the cart or.
b)paying an invoice for a product / service in the client area that has recurring payments.
Creating a second paypal account is simply not possible as it would require a new bank account and credit card etc.
This one is driving me nuts.
