Error 404 to checkout paypal

Hi, I install whmcs brige on my wordpress, with a paypal payment module but i have a problem Next by or I spend to make the payment its walking or not

I explain, when I display the invoice and click on my paypal button it works, the link is:
http://test.mail-exchange.ch/mail-exchange-shop-2/?ccce=viewinvoice&id=101

But when I want to make my payment come the Mass Payment page I am directing to a 404 and the url is:

http://test.mail-exchange.ch/mail-exchange-shop-2/viewinvoice/?id=101

Can you tell me what I need to do to have everywhere the link works, or in which page change the code if necessary

Thank’s Pexys Team
