# Undefined array key “public”

 * I’m getting the following in my system log when I edit my content control settings.
 *     ```wp-block-code
       PHP Warning:  Undefined array key "public" in .../wp-content/plugins/content-control/classes/Controllers/RestAPI.php on line 88'
       ```
   
 * I think the problem originates from a plugin I have recently installed which 
   registers a taxonomy without specifying a value for “public” in the $args. Checking
   the WordPress code I can see that the defaults are not set in WP_Taxonomy::set_props
   until after the register_taxonomy_args filter call. Therefore, RestAPI::modify_type_force_show_in_rest
   should not assume that $args[‘public’] exists. Specifically, the if statement
   at line 88 should include an isset condition first (as it already does for the“
   show_in_rest” value of $args in the previous if).

 * Just changed it to
 *     ```wp-block-code
       		$is_public = isset( $args['public'] ) && $args['public'];		// Check if this is a private taxonomy.		if ( ! $is_public ) {			if ( $include_private ) {				$args['show_in_rest'] = true; // Enable REST API.			}		} else {			$args['show_in_rest'] = true; // Enable REST API.		}
       ```

 * That clears the error message I was getting.
