 * is MCFormWidget installed by a different MailChimp (MC) plugin that this plugin
   relies upon?
 * `[Tue Jun 18 00:35:29 2013] [error] [client 75.51.145.154] PHP Fatal error: Class'
   MCFormWidget' not found in /var/www/vhosts/fake.example.com/httpdocs/wp-includes/
   widgets.php on line 324`
 * I didnt grep any instances of the text MCFormWidget in the entire wp codebase
   or plugin dir.

 * The file MCFormWidget.php exists under `bigmailchimp/classes/MCFormWidget.php`.
   The widget is registered on line 75 in `bigmailchimp/bigMailChimp.php`.
 * Please give more information about your installation, any themes/plugins you 
   are using. Also, a link to the site you are trying to work on can be useful. 
   BTW is there a reason for not upgrading outdated PHP? PHP 5.2.6 is over 5 years
   old.

 * I got the EXACT same error after installing this plugin! Did you find a solution?

 * The plugin now supports PHP 5.2 which does not support many of the new features
   that enable us to create faster code.
 * [Here is why not to use PHP 5.2 or earlier](http://bigemployee.com/stop-using-php-5-2/)
