 * When I try to activate the plugin (installation successful) I receive the following
   error message and the plugin doesn’t activate.
 * Fatal error: Cannot redeclare class paypal_class in /home2/xxxxxx/public_html/
   yyyyyyyyyy/wp-content/plugins/event-registration/paypal.class.php on line 93
 * I’m using the Graphene Theme.
    Can somebody help? Thank you

 * You may have another plugin that is using paypal.class.php as well. Deactivate
   your other plugins temporarily to work through and locate the conflict
