Manage WordPress Plugin

Activate, deactivate, update or delete a plugin that is already installed on a connected WordPress site.

It switches off plugins the site does not need; an unused analytics or tracking plugin keeps loading scripts on every page. Deactivating leaves the plugin and its settings in place, so it can be switched back on; delete removes its files, and an ACTIVE plugin is refused unless you deactivate it first. `plugin` is the file path from wordpress_list_plugins (folder/file.php).

If activating fails, the reply now carries the real reason and a writability check: page cache plugins need wp-config.php and wp-content to be writable, and on hosts where they are not, no cache plugin can be enabled at all.
