I added it like this and so far it seems to have fixed the problem.

		// ensure is_plugin_active() exists (not on frontend)
		if( !function_exists('is_plugin_active') ) {
			
			include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
			
		}		
		
		// bail early if not a plugin (included in theme)
		if( !is_plugin_active($basename) ) {

			return $transient;
			
		}
