# WP Multisite – Lightbox settings not saving

 * I ran into some problems trying to use the plugin in a multisite environment.
   
   On the main site everything works fine. On a child blog I get a PHP Warning saying`
   Warning: array_merge(): Argument #2 is not an array in /wp-content/plugins/responsive-
   lightbox/responsive-lightbox.php on line 78` and “Lightbox settings” will not
   save.
 * Any suggestions?
    thx!

 * Whoops, just realized:
    the problems only occur when I network-activate the plugin.
   With single-site-activation everything’s good.

 * It’s just not multisite compatible. I’m adding this to our to-do list for RL.
