 * Hi – thanks for your great plugin
 * I’ve got Pluging Organizer on a WP Multisite Network
    and a MU Plugin PluginOrganizerMU.
   class.php
 * I noticed today a massive build-up in the wordpress root error log
    and activating
   plugins has had issues
 * PHP Warning: array_search() expects parameter 2 to be array, string given in /
   home/xxx/public_html/wp-content/mu-plugins/PluginOrganizerMU.class.php on line
   410
 * line 410 is
    $newPluginListOrder[] = array_search($pluginFile, $activePlugins);
 * hoping it is obvious what needs to be changed.
 * thanks

 * I moved (copied/deleted) the PluginOrganizerMU.class.php from the plugin/lib/
   folder and replaced the one in mu-plugins
 * seems to have resolved issue.
