 * Hi,
    mPDF is using a PHP extension your server is missing. Please ask your host
   to install the extension. For more information take a look [here](http://us2.php.net/manual/en/mbstring.installation.php).
 * This isn’t a default extension, so I will try to do some error handling to resolve
   this issue.
