Product Stock Alert emails are not sending- the site has been live for years but they didn't want this feature active before.
Other emails such as new membership and password changes are sending
Cron appears to be working - the "catalog_product_alert" job is scheduled and appears to be running every minute. The product_alert_stock table shows who is signed up and shows that they have been notified, but they don't get an email.
Looking at email reports in cpanel suggests that no emails have been sent - they are not pending or blocked or successful. But other emails work ok so don't think there is anything wrong with the actual email on the server.
Is there anything else I need to check? Thanks very much!
