 * Hi guys,
 * I get this PHP warning with the plugin:
 *     ```
       Warning: Invalid argument supplied for foreach() in .../wp-content/plugins/speed-booster-pack/inc/core.php on line 472
       ```
   
 * I am using Launchpad plugin ([https://wordpress.org/plugins/launchpad-by-obox/](https://wordpress.org/plugins/launchpad-by-obox/))
   and get the above error.
 * I know, there is no need for Speed Booster Pack plugin being enabled on that 
   website when Launchpad is on, however, this is a WP multisite and Speed Booster
   Pack is network enabled.
 * I think it would be good practice to check if affected `$wp_styles` global is
   set first. [https://github.com/wp-plugins/speed-booster-pack/blob/master/inc/core.php#L472](https://github.com/wp-plugins/speed-booster-pack/blob/master/inc/core.php#L472)
 * Thanks and regards,
 * Oliver
