SMTP emails not working
One of the main reasons for upgrading to 2.6 was because the SMTP emails stopped working on 2.3 when I upgraded PHP to v7.0.
I read that the version of PHPMailer in Vanilla 2.3 needs updating and by upgrading to 2.6 that would solve it.
The error I was getting before was "SMTP Error: Could not connect to SMTP host".
But, now i've upgraded, the emails still don't appear to be getting sent!
