 * I tried adding the plugin to a second site on the same server, but as soon as
   i drop the file in wp-content folder the site somehow links to the other site
   using the plugin.
    And the sidebar has the widgets from the other site too.

 * Hi George,
    Sorry for the delay. If you haven’t figured this out yet, the answer
   is to set the salt key in your wp-config.php file, e.g.:
 *     ```
       define( 'WP_CACHE_KEY_SALT', 'site-1' );
       ```
   
 * The salt can be any string; I would advise making it descriptive of the site 
   in some way, like the domain name.

 * Thanks. Should add that info in the FAQ or installation page.
