Media Cleaner: FAQ

Navigation Close

Remember to always check your PHP Error Logs.

– js_composer: yes, it was used some time ago by Visual Editor, but not anymore
– wplr-tmp: yes, totally
– wpseo-redirects: if you are using redirections in Yoast SEO, you should not delete this
The plugin has been extremely optimized so now this depends mainly on your WordPress install and your server. With PHP, for each page load (and therefore for each asynchronous requests, in the case of my plugin), WordPress loads itself every time. All the plugins are also being loaded and might even run a task. Unfortunately, Media Cleaner cannot do anything about it. You can make it faster by checking out a few options, but the best is to enhance the system. I am trying to keep an article about accelerating WordPress here.
It would be way too dangerous. A bad update, the page builder disabled temporary or another mishap and the WordPress install will be basically destroyed. So it’s better not. Also, having this running in the background would slow down the site every time a visitor would load the page (which is really isn’t good), might also crashs. WordPress was not really made for running background tasks (it can only reacts on specific actions) so it’s better to avoid it with such a plugin as Media Cleaner.

That said, if you really want to run a scan in the background every once in a while, you can do it using WP-CLI, and manually create a task (cron tab) on your server. You can ask your developer or system administrator to do this.
There is now a setting for it. Have a look at the Media Cleaner settings :)

Handling specific issues

If you would like to handle special cases and additional detections of file usage, here are a few code snippets that you could use or adapt to your specific needs. You can add those snippets directly using the Code Snippets plugin (or add them into your functions.php file directly).

Images in category’s descriptions

add_action( 'wpmc_scan_once', 'wpmc_scan_once_post_categories', 10, 0 );

function wpmc_scan_once_post_categories() {
	global $wpdb;
	global $wpmc;
	$descs = $wpdb->get_col( "SELECT description FROM {$wpdb->term_taxonomy} WHERE taxonomy = 'category'" );
	foreach ( $descs as $desc ) {
		$urls = $wpmc->get_urls_from_html( $desc );
		$wpmc->add_reference_url( $urls, 'CONTENT (URL)' );

Overriding the Cleaner’s decisions

There are some cases where you would like to avoid the scan of certain files (owned by the administrator), or maybe the contrary and decide that all the Media entry with a certain name should be deleted. Everything is possible through those two filters:
