uninstall.php

<?php
/**
 * Uninstall handler for GoDAM.
 *
 * WordPress runs THIS file — in isolation, with WP_UNINSTALL_PLUGIN defined — when the plugin
 * is deleted, instead of including the main plugin file. Doing cleanup here rather than via
 * register_uninstall_hook() is deliberate and fixes issue #1146:
 *
 * register_uninstall_hook() makes WordPress `include` godam.php during deletion, which
 * bootstraps the entire plugin AND loads the bundled WooCommerce Action Scheduler. WordPress
 * then deletes the plugin's files, so on `shutdown` the now-dangling references (Action
 * Scheduler's shutdown callback, the class autoloaders) fatally try to load classes that no
 * longer exist. That surfaces as a "Deletion failed" error under Query Monitor, or as a
 * "502 Bad Gateway" on servers that buffer the response until shutdown — even though the
 * plugin is actually removed (a page refresh confirms it). Running cleanup from uninstall.php
 * never bootstraps the plugin, so those references simply do not exist at shutdown.
 *
 * @package GoDAM
