Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
This issue is related to the PRO plugin, and it seems that your account is currently on a Free account. Your previous Rank Math PRO subscription has already ended last month, so you currently have no access to the PRO updates.
Here’s a guide you can follow: https://rankmath.com/kb/fix-pclzip-err-bad-format/
To continue using the PRO features and receive updates, you’ll have to purchase a new plan from here: https://rankmath.com/pricing/
Don’t hesitate to get in touch with us if you have any other questions.
