I have contacted my webhost support and they have told me nothing is wrong. </p> https://www.machform.com/forums/topic/my-form-suddenly-stopped-working-and-shows-the-following-error-after-submitting#post-23085 Fri, 10 Apr 2015 17:23:49 +0000 yuniar 23085@https://www.machform.com/forums/ <p>The PHP mail function on your server doesn't seems to be working properly. I suggest to contact your hosting tech support and let them know, since this is server issue.</p> <p>Alternatively, try configure your MachForm to use SMTP server. </p> https://www.machform.com/forums/topic/my-form-suddenly-stopped-working-and-shows-the-following-error-after-submitting#post-23083 Fri, 10 Apr 2015 17:21:29 +0000 mojoe 23083@https://www.machform.com/forums/ <p>Error sending email!<br /> Warning: Cannot modify header information - headers already sent by (output started at /home/bizcentralcomau/public_html/form/includes/helper-functions.php:794) in /home/bizcentralcomau/public_html/form/embed.php on line 116 </p>
