 * Hello,
 * After I upgraded a plugin on the website, the wp-rollback plugin started to throw
   errors:
 *     ```wp-block-code
       PHP Recoverable Error: Uncaught exception 'TypeError' with message 'strpos(): Argument #1 ($haystack) must be of type string, stdClass given' in /app/web/wp-content/plugins/wp-rollback/wp-rollback.php on line 484, request: GET /wp-admin/plugins.php, request_id: b89a274f8c5c34a42774f7bc4f1d2b5a
       ```
   
 * Thanks,
