Fatal error when wp_editor used in front-end ( solution included )

Hi,

When a theme/plugin is using wp_editor() in the front-end there will be a fatal error coming from Shortcodes Ultimate since admin-only function, is_plugin_active(), is being called.

File in question is inc/core/tools.php, line is 252.

if ( !is_plugin_active( $paths[$addon] ) ) return false;

Solution is to simply check if it’s in admin first:

if ( ! is_admin() || ! is_plugin_active( $paths[$addon] ) ) return false;

Or you can switch the is_plugin_active() with a check for function from the add-on plugins ( function_exists() ) to see if it’s active.
