File not found: minify-admin-purge-3-1-9.min.js

Replies: 0

I get the following error in my browser console;
http://localhost/wp-content/plugins/wp-optimize/js/minify-admin-purge-3-1-9.min.js net::ERR_ABORTED 404 (Not Found)

I can see that this js file is being enqueued, within wp-optimize/minify/class-wp-optimize-minify-admin.php :

wp_enqueue_script(
			'wp-optimize-minify-admin-purge',
			WPO_PLUGIN_URL.'js/minify-admin-purge' . $min_or_not_internal . '.js',
			array('jquery', 'wp-optimize-send-command'),
			$enqueue_version
		);

The file no longer appears to exist in the plugin directory (version 3.1.9).
