I have tried a number of fixes with no luck. I’m on a system that Uses CPanel - i.e. I don’t have direct command line access to some things. But, I am able to edit a PHP.ini file; I went in there and turned error logging on and set it to write to a specific file. I’m getting nothing in that file - well, there’s no file at all.
I have also started a new campaign - this time I left the email address in the ‘From’ field that the system automatically populated (a listsrv@… email). So I would assume that this is a valid email. (I had tried a few other emails without any luck.) I’m still getting the exact same errors: “could not instantiate mail function”.
Without being able to see some additional logging info from the system, I’m at a loss as to where to look next or what to try.
Oh, I also did copy the ‘config_extended.php’ file and modify it to match most of my prior settings, and then renamed it to ‘config.php’. Still no luck.
