Mailer Error: Could not instantiate mail function.

Question

I am using ChronoForms on both the live and development sites below. The development site will not send contact form messages despite the fact that the settings are the same as the live site.

Any suggestions/ideas on how to resolve this problem?

Mailer: PHP Mail (both sites)
PHP Version 5.6.25
URL: http://autumnofsarasota.com/newsites/aaa/contact.html

We are sending using the same FROM NAME and FROM EMAIL (noreply[at]autumnofsarasota[dot]com) on both sites. The TO and BCC are the same on both sites.

Debug Output:
