Hello,
Thank you for contacting us. We apologize for any inconvenience this issue may have caused.
We can see that your Rank Math PRO subscription has expired without being renewed.
The PCLZIP_ERR_BAD_FORMAT error is usually due to trying to update the Rank Math PRO plugin while connected to a free account. You can refer to this article: https://rankmath.com/kb/fix-pclzip-err-bad-format/
You will need to purchase a new Rank Math PRO subscription to have access to recent updates of the premium plugin: https://rankmath.com/pricing/
We hope this helps. Please let us know if you have further questions or concerns.
Thank you
