A PHP mail form that used to work is no longer working. The form had not been used for awhile because it was not needed, but now it is.
The form data is collected from
http://www.animeusa.org/volunteering_sign_up.php
and sent to this page for validation and emailing.
http://www.animeusa.org/volunteering_submit.php
When the user sumbits the form you now receive these messages
Warning: send(Net/SMTP.php) [function.send]: failed to open stream: No such file or directory in /usr/local/lib/php/Mail/smtp.php on line 206
Warning: send() [function.include]: Failed opening 'Net/SMTP.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /usr/local/lib/php/Mail/smtp.php on line 206
Fatal error: Cannot instantiate non-existent class: net_smtp in /usr/local/lib/php/Mail/smtp.php on line 210
Would there have been some change to the servers regarding php that would cause the form to stop working?
