I have tryed all the fixes on here that I have seen. It still has a problem. It will send to only one of the lists even though I am telling it to send to all the lists. It never sends to more than one. I have ten lists and set it up to work with 10 lists. Also there is only 39 users. It is for a christian school and each user is subscribed to different lists.

I am getting the same error.

A few months ago, I had the problem with the following error:
"Mailer Error: Language string failed to load: instantiate"

I did the line 4 fix; and it got better until today. I tried the line 24 fix described here: and developed the new error:
"Mailer Error: Could not instantiate mail function."

I have resolved my issue... turned out it may have been a peculiarity of hosting with GoDaddy.

Following a tip found on this forum:

Except that the replacement of:
var $Mailer = "mail";
var $Mailer = "sendmail";

was made in:

On line: 44 (not 109)

This error does not mention a language file problem, how is it related?

After setting 3 variables ,I got it.
1 define("PHPMAILERHOST",'****');
2 $phpmailer_smtpuser = '******@***';
3 $phpmailer_smtppassword = '*****';

Rachel's solution of changing 'mail' to 'sendmail worked for me!

Line 48 in PHPList 2.10.11

Correction to my last note: I had a 4.5MB attachment in my message that was failing. Usually my newsletter has <1MB. I removed the attachment and it was working again. Had to include it as a link to a hosted file rather than a direct attachment.
