online payment link does not work

Probably after update, it does not work. The error message is; 

This order’s status is “Pending payment”—it cannot be paid for. Please contact us if you need assistance.

Can you send me your WordPress logins so i can try? I don't see problem in my end i just tried. 

Looks like some payment gateway issue https://wordpress.org/support/topic/pending-payment-it-cannot-be-paid-for-3/

Which payment gateway are you using? You need to provide us access to troubleshoot problem as its not with plugin itself this is conflict with some other plugin, your payment gateway or any other plugin is disabling checkout behaviour for pending payment status orders

The status Pending payment is right and that's what order is in when its created by RepairBuddy WordPress plugin.
