Hello mianel,
Please follow the instructions below:
1) Please check the plugin settings
‘/wp-admin/admin.php?page=contact_form.php’ => ‘What to use?’ =>
change the lines from wp-mail to mail and vice versa.
2) email messages can be marked as spam on the server. Please choose
another email instead of the admin’s one (‘Use this email:’ block) –
for example, gmail or similar. If the message is sent, it means that
email filtering is set on your server.
3) Did you get any notifications about new users registration? If not,
perhaps email sending is not set. if so, you should install an extra
plugin called WP-mail-SMTP and configure it. Afterwards you should
send a test email from this plugin and you will see if the plugin logs
have errors.”
Kind regards,
Support Team
