Could Not Instantiate Mail Function

Hi everyone,

This used to be working and I didn't make any changes and suddenly it's not working.

Now when I perform any actions (I have MultiVendor v 4.3.3.SP1) that should notify the vendor, I get the following error:

ErrorMessage could not be sent.

Mailer Error: Could not instantiate mail function.

And I don't know why or how to troubleshoot it. I've done some searching and found 100 different inquiries of people with the similar problem but none of the solutions work for me (some of them are quite confusing too).

I'm hosted through ""

Any help please??

Speak to host , see if anything has changed on server

I have had this issue a few times.

"Can't instantiate" usually refers to the mailer class's attempt to load the relevant delivery method (PHP mail, Sendmail or SMTP). Which setting are you using?
