Hi, I stumbled across this yesterday and it works. Thank you for following up!

Error: Call to a member function isRecurring() on null in /home/sites/1a/3/35a4cc6b02/public_html/whm.tech1uae.com/vendor/whmcs/whmcs-foundation/lib/Billing/Invoice.php:0Stack trace:#0 /home/sites/1a/3/35a4cc6b02/public_html/whm.tech1uae.com/vendor/whmcs/whmcs-foundation/lib/Invoice.php(0): WHMCS\Billing\Invoice->cart()#1 /home/sites/1a/3/35a4cc6b02/public_html/whm.tech1uae.com/includes/gatewayfunctions.php(0): WHMCS\Invoice->getGatewayInvoiceParams()#2 /home/sites/1a/3/35a4cc6b02/public_html/whm.tech1uae.com/admin/invoices.php(0): getGatewayVariables('mailin', 5082)#3 {main}

In fact, I've just checked and it also gives the error when I click on a previously paid invoice for the same client.

Hi all, new to the community. Having a strange issue with WHMCS. When I click on an unpaid invoice for a client that has no services, I get the attached response. This happens with two of my clients. Does anyone know how I can fix this please? Thanks!
