 * I just tried to install the plugin on a fresh copy of WP 4.0 and I got this error:
 * Warning: require(__DIR__/client.php) [function.require]: failed to open stream:
   No such file or directory in /home/dpsi2013/public_html/bevstorage/wp-content/
   plugins/marketo-forms-and-tracking/init.php on line 21

 * Hi pacomelo,
 * I have to apologise – these emails had been popping into spam so we missed them.
   The only other thread in the forum alerted to their issue on twitter so now we’ve
   checked them and we found yours.
 * The error is likely to be because you are running an old version of PHP. the 
   __DIR__ constant has only been available since PHP 5.3.0.
 * Did you get over the issue or is it still a problem? If it is still an issue 
   then upgrading PHP to 5.3+ is the answer.
