Human readable explanation of the error message: phpMailer library tried to send a message using the php mail() function and the php mail() function returned “false”.

Two most common causes of this error message are - server settings - phpmailer libraries used within Oxwall.

Since mail functions are part of the PHP's core, first of all make sure that PHP was configured/compiled correctly on your server to send emails.

Run following test to see whether php mail script is working.

Create a file called testing_mail.php in /public_html/ directory on your server. Add one of the following codes into this file:

1.

 <? $headers = 'From:any_sender_email@example.com'; mail('recepient@example.com', 'Test email using PHP', 'This is a test email message', $headers, '-fany_sender_email@example.com');?> 

2.

 <?php $to = 'nobody@example.com'; $subject = 'Test email using PHP'; $message = 'This is a test email message'; $headers = 'From: webmaster@example.com' . "\r\n" . 'Reply-To: webmaster@example.com' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); mail($to, $subject, $message, $headers, '-fwebmaster@example.com'); ?> 

Run created file by opening www.yoursitename.com/testing_mail.php in any browser. You will see

1. Check whether phpmailer library is installed/enabled/configured
2. Check whether php mail() function is installed/enabled/configured

Best way to check this, is to contact your hosting provider.
