Slim Application Error

Things are getting a bit rough now with PHP but I am sticking with it. With Forms and Email I got the following error: Slim Application Error

The application could not run because of the following error:

If you are using GMail then take notice that GMail's SMTP requires encryption. Use Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl").

I had exactly the same application error . Which occurred in this line of code:

$transport = Swift_SendmailTransport::newInstance('usr/sbin/sendmail -bs');

I did not specify the correct path. It is necessary to add a forward slash (/) to the beginning of this path before the usr directory as follows:

$transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs');

The above line of code resolved the problem.

Thank you, Peter, I did not make the same mistake as you did, but your answer led me to review my code thoroughly.<br> Fortunately I found the error, which was, instead of: [some_code]('/usr/sbin/sendmail -bs')[/some_code]. I've written [some_code]('/user/...')[/some_code] after fixing my mistake with: <br>

$transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs');

the message was send succesfully, thank you!
