Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
It seems like your subscription to Rank Math PRO already expired last June 18, 2023.
Unfortunately, updates to Rank Math PRO plugin will no longer be available until you re-subscribe to our plans again. Can you please share the email address of that Free account so we can merge it with your PRO account?
We have covered this topic here: https://rankmath.com/kb/fix-pclzip-err-bad-format/
If you still have any questions, just reply and we will be more than happy to clarify any doubts you might have.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
