 * I have the same exact problem when trying to activate the plugin.
 * I have a network of 3 sites and when I try to activate it network wide or by 
   site I get this error and this message:
 *     ```
       Notice: Undefined index: master_site_setting in /home/shzion/public_html/wordpress/wp-content/plugins/multisite-post-duplicator/addons/restrictSites-mpd-addon.php on line 325
       ```
   
 *     ```
       The plugin generated 1260 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
       ```
   
 * On the pages/posts editor I get the same error for each site that I can duplicate
   my page/post.
 * I have not tried to duplicate them but this is not usable right now for me.
 * I’ll be glad if you can help us to solve this problem because this plugin is 
   the only one that works with ACF and meta data without paying an extra $100
