Object Cache Pro (WordPress plugin)

Object Cache Pro is a must-use plugin, so you can only see it at the backend at Plugins » Must-Use

Object Cache Pro is a caching plugin that might be specific for CloudWays. Maybe it's a rebranded version of Redis Object Cache, as these two names are used a lot together.

Two parts?

It seems to consist of two parts:

• Files & folder at wp-content/mu-plugins with Redit in the name
• File object-cache.php at wp-content.

When only the last file is present, errors are generated (like on the CLI when you use a WP-CLI command), like

objectcache.critical: Failed to locate and load object cache API

objectcache.critical: Failed to locate and load Object Cache Pro plugin

Must-Use plugin

As it is a must-use plugin, you can only see it at the backend at Plugins » Must-Use. See the image on this page for details.

Additionally, you can only remove it by removing the files, not through wp plugin uninstall or so.

Removal

rm wp-content/object-cache.php
rm -rf wp-content/mu-plugins/redis*
