I recently upgraded my WordPress to 3.1 (from 3.0.5) and Web-Invoice to 2.1.0.
A problem occured where the Next Due Date section in my Recurring Billing didn't show the Due Date but showing today's date.
I checked all invoices and the due date is correct. It's just in the overview page where the Next Due Date section seems to be wrong.
Hope there a solution for this issue.
Thank you.
