No longer getting mail

Hello hosseint,

Please follow instructions below:
1) Please check plugin’s settings ‘/wp-admin/admin.php?page=contact_form.php’
2) It is possible that email messages are detected like a spam on the
server. Instead of administrator ’email’ choose another ’email'(‘Use
this email:’ block) – for example, gmail account or similar. If the
message will be approved (it will be sent), then you’ve an email
filtering configured on your server.
3) Pperhaps you didn’t configure email sending. Then You need to
install an extra plugin called WP-mail-SMTP and configure it.

Kind regards.
