Hi @rchadwick,

thank you for providing the debug log.

As you can see the error is related to the certificate. There are a few possibilities as to what the actual problem is… please visit this Troubleshooting guide, more specifically the “Certificate verification failure” section.

Verify the things they suggest and you should find what is causing the issue for you.

Let us know what the solution for you was.

Have a nice day!

Hi @rchadwick – As Gregor suggested you’ll need to fix your certificate. If you’d like to use a self-signed certificate and disable SSL verification, you can use this custom codes. Please note that it is compromising your security. In case it helps, here’s how to add custom codes like that.

I hope this helps!

It helps. It’s on my to-do list today to look into those custom codes. Will they survive an update?

I have a problem that the importer demo not working at all and I’m not perfect with coding so plz tell me what should I do, I’m not sure how to use

Hi @ayatyoussef – This is a forum for WP Mail SMTP. If you’re having issues with the demo import plugin, please reach out to their support forum.

Thanks!

Hello @ayatyoussef and @rchadwick
Hope you are doing well,

`on this file location plugins/wp-mail-smtp/src/Processor.php

on this function: phpmailer_init (consider Replacement 1 and Replacement 2) as below.

public function phpmailer_init( $phpmailer )
{
Replacement 1:
replace this line: $mailer = $options->get( ‘mail’, ‘mailer’ );
with this line: $mailer = ‘mail’; // I know this is static but it’s quick solution

Replacement 2:
replace this line: if ( ‘smtp’ === $mailer ) {
with this line: if ( ‘mail’ === $mailer ) {
}

Now check with Email Test
Let me know if it helps
Thanks
