Our forum is behind a membership wall, but since updating to the latest version of bbPress forum users who have signed up for new topic notifications under various forums are not receiving those notifications. We have bbPress 2.6.5, bbPress Private Groups 3.8.3, and GD bbPress Attachments 4.1. We use SendGrid for mail delivery so I can see that topic reply notifications are being sent and received. Any ideas where I can look? I’ve gone into the “Repair Forums” and “Upgrade Forums” functions and run everything that looked applicable, including upgrade user topic and user forum subscriptions. Any advice would be greatly appreciated, thank you.
