Plugin does not send emails

We found out why it did not work:

login-with-ajax is incompatible with the WP mail SMTP plug-in wp-config.php option:

Dashboard -> WP mail SMTP
tells:
SMTP Password
[ …… ]
The password is stored in plain text. We highly recommend you set up your password in your WordPress configuration file for improved security.
To do this add the lines below to your wp-config.php file:

define( ‘WPMS_ON’, true );
define( ‘WPMS_SMTP_PASS’, ‘your_password’ );

After removing those 2 lines from the wp-config.php file login-with-ajax started to send the emails.

Hi all, sorry for the late reply due to the holiday season.

I just tested out the suggestion by @janmartin3 but for me this works fine. Also, we don’t do anything special with emails, we use wp_mail for registration emails and the remember me email is triggered by a WP function, not us.

I’d suggest you try this with other plugins disabled (and use a default WP theme) which you can do just for yourself using my WP Safe Mode plugin.

Also, are you using Gmail by any chance? I’ve found it to be VERY unstable now with SMTP, and later this year it will cease to allow SMTP for sending emails anyway so I’d suggest connecting via WP SMTP’s oAuth option.
