I have built a form and it seems to be fine until I hit the Submit button.

I want to send a simple email confirmation message using the default format. This is option 1 in Settings/Confirm Page.

The process fails with the following displayed on the page where the form is embedded:
Fatal error: Call to undefined function quoted_printable_encode() in /home/content/s/l/i/slimjim/html/2015IIBC/2015-IIBC-Reg/fbapp/php/mailer.cls.php on line 104

The form validation seems to work, so I don't think its path problems.

No email is sent either to the user email or the the notification address.

I have done a trivial form before to flush the process, so I don't think I have made any gross errors.

One other thing of interest. I am unable to test this on WAMP because of the following:
The requested URL /2015-IIBC-Reg.php was not found on this server
although it is in the same directory.

If I had to guess, you are running PHP 5.2.17 but PHP 5.3 is required.

Thanks for the quick response, Scott. That did it.

Don't you ever take a day off? I'm working on this for my wife's event, so I don't have a choice!

Hi iv same error. How do I check what version of php im using?
Thanks

Your hosting control panel should list it.

Thanks Its working again, though it wont send it from the address i set it too. Such as info@domain.com instead it sends it from info@www.domain.com

I've had a web form working perfectly on my web site for some time using a MySQL database (php 5.3) and not S Drive. It was immediately trashed as soon as I upgraded to the latest version with the error in 'mailer.cls.php' file.

I copied the single file 'mailer.cls.php' from my backup over the new one and it restored the form back to a fully working order.

This is a problem with 'quoted-printable-encode' and is described on this web page together with a suggested solution :-

http://php.net/manual/en/function.quote … encode.php

So I bought the new (ok its from 2015) form builder and spent hours trying to resolve a nagging problem from the previous Flash form builder I got somewhere years ago and my first attempt to submit and I get this same error.

Fatal error: Call to undefined function quoted_printable_encode() in /home1/tntrenta/public_html/TNT-Res-Form1/fbapp/php/mailer.cls.php on line 104

I looked thru the posts here and I see the suggestion of verifying the php level. I was pretty sure my hostmonster account was at php ver. 5.4? But I am not certain. Was there any other issue that could be causing this error?

What is the URL to the form?

I was also having the same problem getting the same: Fatal error: Call to undefined function quoted_printable_encode().
I had two forms on two different sites but on the same server, (BlueHost). The older one worked which was built with an older version of Coffee Cup Web Form Builder, a newer one built with the latest version of the software would not work and threw the error. By replacing the following code from the file 'mailer.cls.php' with code from the older version's file of the same name the problem was fixed.

This is from the newest version at line 104 and was causing the error:

function SetMessage ( $message ) {

$this->message = quoted_printable_encode( $message );
}

and was replaced with:

function SetMessage ( $message ) {

$this->message = wordwrap( $message, 70 );
}
