CiviCRM: 4.7.3 Joomla: 3.4.8 PHP: 5.5.45
None of my Membership Contribution confirmation emails are being sent. It doesn't matter if the person pays via PayPal, or is using Pay Later, they don't go out.
I receive the confirmation from PayPal that a membership fee payment has been made, but no other communications from CiviCRM, and I do have the email setup for CC to me.
Scheduled emails are being sent, as people are coming to the website to renew their memberships; and I've done the Outbound email check to verify that CiviCRM can send emails through the server.
This was working fine until August 2015, about the time I upgraded to 4.6.8 or so.
I kept up with the upgrades thinking that it was a fluke, but have not seen any corrections. I am not seeing any PHP errors, and I have been testing this using dummy names and a real email address to see if I can force any error messages.
I'm basically at a loss, and with a major event coming up, I need to have confirmations sent when people pay. I haven't tested with event confirmations yet, but that's the next step.
UPDATE: Just tested with events, and Confirmation emails are being sent to the attendee, and the treasurer so, at least for PayLater, the confirmations are going out for events.
UPDATE - 2016-03-18 upgraded to 4.7.4, and had to revert out of it as it broke the 'pay later' display as described in CRM-18118.
Installed the patch to CRM/Contribute/Form/Contribution/Main.php as shown in 18118, and also patched CRM/Contribute/Form/Contribution/Confirm.php as showin in 18118.
The live page shows the Pay Later, and when tested sent an email to confirm the renewal, and show an invoice. The CC email copies were sent properly. I am not going to reinstall 4.7.4 as it appears something else in that release broke the fixes in 18118.
