failed to open stream in php
===

i get this error on a simple `include` method:

    Warning:  include(/home/content/70/8352870/html/sites/mysite.com/preview/wp-content/themes/site-theme/mail/class.phpmailer.php)
    [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory in /home/content/70/8352870/html/sites/mysite.com/preview/wp-content/themes/site-theme/mail/send-message.php on line 5

I've included the file using this

    <?php
    $path = getcwd();
    include $path.'/class.phpmailer.php';
    ?>

I get the same error without using `getcwd` method but this:

    include 'class.phpmailer.php';

    Warning:  include(class.phpmailer.php)
    [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory in /home/content/70/8352870/html/sites/mysite.com/preview/wp-content/themes/site-theme/mail/send-message.php on line 10



Obiouvsly I checked the files are located here

    mysite.com/preview/wp-content/themes/site-theme/mail/
    class.phpmailer.php
    class.pop3.php
    class.smtp.php
    send-message.php

Where I'm wrong?
