I have 155f running and I have not changed much here in terms of anything that I can think of in the past few months. My site has been VERY quite for the last 3 months due to a down time with products as my items are not available year round.

Needless to say, I cant point to an exact day when I lost the ability to send emails from my admin panel.

Anytime I try to send an email from the admin panel weather it is via the tool menu or to update the status of an order, I get this error across the top of my screen in red. I copied and pasted it below:


"ERROR: Failed sending email to: "ZEN Test ACCOUNT" with subject: "test" SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting"


I went to the link provided and it says to turn on the debug logging.

Can anyone help with some detail as to how to go about changing the debug level to "2" as suggested in the wiki support article?

Also, can anyone help with telling me where this file is located that I would need to change as well as the output of the actual debug log?

Lastly, if an expert has a suggestion regarding possibly updating the phpmailer and if that move is safe (I don't have the time to update to the latest zencart for at least 4 months), maybe that will be a possible say to go. I do not know the version number of what came with 1.5.5f (is there a way to tell what it is??), but maybe Im running something outdated. I figured if this was a wide spread thing I would have seen others posting about this which also make me think this might be my hosting company changing things or a change to gsuite's backend...but again, I cant be the only one with this particular setup.


Many thanks in advance for any help that you can provide.

ZC version 155f
PHP version 7.1.2.2
