PHP 8.0 Support

Hi,

We recently tried to migrate a site to PHP 8.0. However, when we did this, we encountered a fatal error which we think is coming from your plugin.

PHP Fatal error:  Uncaught TypeError: closedir(): Argument #1 ($dir_handle) must be of type resource or null, bool given in /var/www/wp-content/plugins/simple-lightbox/includes/class.utilities.php:1319

If we switch back to PHP 7, we no longer get the issue. Does your plugin support PHP 8.0?

Any help much appreciated.

Thanks,
