Just update to 8 and also the website server went down.
I guess one of the 2 events cause my Testing Sending Process to not complete and return this error.
_Error sending message “MY TITLE" to MY_TEST_EMAIL SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/TroubleshootingSMTP server error: Failed to connect to server SMTP code: 110 Additional SMTP info: Connection timed out_
Was working perfectly before these 2 events, no settings modified — Any ideas!
