Transient and redis cache issue

The default groups are: 'counts', 'plugins', 'themes'

If your diagnostics show many other groups, then some thing is adding them.

Hmm for what reasons would someone what these in to ignored groups? Where could they have added this nothing in the wp-config.php, using Cloudways anything you are aware about that they add from their end into the ignored groups? Or would it be coming from other plugins?

I can’t answer any of that. You can search for add_non_persistent_groups() to see who’s adding the groups.

No easy way to search for a line of code in all the plugins files via SFTP or any suggestion to easier locate and debug?

SSH + find + grep ???♂?

Can not find anything in these plugins and respective php files which is adding any other groups to ignore.

If those files don’t help, I’d add logging to wp_cache_add_non_persistent_groups() to see who’s doing it.

How would I add logging to wp_cache_add_non_persistent_groups()

This is outside the support scope for this plugin. I’d suggest hiring a developer to assist you.

I unloaded WPML string translation plugin and saw only default. Now I activated and seeing this, while all groups before was in ignored. Now it looks more correct, right? Below happened once deactivate and activate the wpml stirng translation plugin.

Global Groups: [
    "blog-details",
    "blog-id-cache",
    "blog-lookup",
    "global-posts",
    "networks",
    "rss",
    "sites",
    "site-details",
    "site-lookup",
    "site-options",
    "site-transient",
    "users",
    "useremail",
    "userlogins",
    "usermeta",
    "user_meta",
    "userslugs",
    "redis-cache",
    "blog_meta"
]
Ignored Groups: [
    "counts",
    "plugins",
    "themes",
    "WPML_ST_Package_Factory"
]
Unflushable Groups: []
Drop-ins: [
    "advanced-cache.php v by ",
    "Redis Object Cache Drop-In v2.0.22 by Till Krüss"
]

<?php

class WPML_ST_Package_Factory {

	/** @var WPML_WP_Cache_Factory $cache_factory */
	private $cache_factory;

	public function __construct( WPML_WP_Cache_Factory $cache_factory = null ) {
		$this->cache_factory = $cache_factory;
		wp_cache_add_non_persistent_groups( __CLASS__ );
	}

	/**
	 * @param \stdClass|\WPML_Package|array|int $package_data
	 *
	 * @return WPML_Package
	 */
	public function create( $package_data ) {
		$cache_item = $this->get_cache_item( $package_data );

		if ( ! $cache_item->exists() ) {
			$cache_item->set( new WPML_Package( $package_data ) );
		}

		return $cache_item->get();
	}

	/**
	 * @param array|WPML_Package $package_data
	 *
	 * @return WPML_WP_Cache_Item
	 */
	private function get_cache_item( $package_data ) {
		if ( ! $this->cache_factory ) {
			$this->cache_factory = new WPML_WP_Cache_Factory();
		}

		$package_key = md5( json_encode( $package_data ) );

		return $this->cache_factory->create_cache_item( __CLASS__, $package_key );
	}
}

@tillkruess Checked production as well with the pro version didn’t deactivate wpml string translation or anything there. Might have been some glitch, but it looks all fine, only default + wpml_st_package_factory is ignored.

Global Groups	analytics, users, userlogins, usermeta, user_meta, useremail, userslugs, site-transient, site-options, blog-lookup, blog-details, site-details, rss, global-posts, blog-id-cache, networks, sites, blog_meta

Non-persistent Groups	counts, plugins, themes, WPML_ST_Package_Factory

Non-prefetchable Groups	analytics, userlogins, wc_session_id
