Since yesterday back-in-stock emails aren’t sent, none of them. The email notifications are enabled in WooCommerce and ‘manage stock’ is switched on for all products, so that couldn’t be the issue.
Now, the email list of interested persons is blank and the emails haven’t been sent. How can I fix this issue and how can I still send the back-in-stock emails to the people that already signed up for a notification for products that are now restocked? There were many and now none of them received an email.
