 * Network Activation of the plugin seems to work.
    The plugin seems to work fine
   on the main primary Network site, but when loading the 2nd site (sub-domain with
   domain mapping) I get the following error on every Admin page and cannot save
   the settings.
 *     ```
       Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/username/example.com/wp-content/plugins/facebook-feed-grabber/ffg-options.php on line 17
       ```
   
 * {domain and username have been changed for privacy}
    the line 17 from ffg-options.
   php
 *     ```
       $this->options = array_merge($ffg_setup->defaults, get_option('ffg_options'));
       ```
   
 * It seems to not be able to retrieve the correct tables/data due to some MU network
   magic I assume. I haven’t tried to use it without the additional domain mapping
   yet, but will give it a try tomorrow.
 * Anyone have any ideas or experience with making MU-compatible plugins?

 * I don’t currently have any multisite experience but I’d love to help work through
   this problem. Probably be Friday or Saturday before I can give this anytime.

 * I de-activated the plugin across the Network as a whole and tried activating 
   the plugin each per child blog and this seems to work as expected, so I guess
   actual MU support isn’t required anymore.
 * I did find out the issue with network-wide activation most likely has something
   to do with the page options and some newer whitelist function that makes it all
   work as FB intends.
