 * The class `PMXI_Plugin` and the function `wp_all_import_pro_updater()` are "hidden" behind a `if` statement:
 * `if ( is_plugin_active( 'wp-all-import/plugin.php' ) ) {`
 * This prevents the php parser to do its job.
 * This script removes the `if` statement, allowing the parser to find these nodes.
