Hi @niklasinpsyde ,
Thank you for your reply. After reinstalling version 6.4.0. everything starts to work again now. Before I update to any other version I want to collect my arrears first (collect overdue payments). Because it had a big impact on many subscriptions (payment dates, subscriptions status and access for my customers to there courses) I’m fixing that currently.
I’m not a hardcore programmer, so what is fixed with the plug-in version you suggest?
