Hello,
We apologize for the issue you are facing while trying to upgrade Rank Math PRO. The error message "PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature" typically occurs due to a few common reasons:
-
Problem with the Zip File: The zip file you downloaded may be corrupted. We recommend downloading the latest version of Rank Math PRO from your account and trying to install it again.
-
Updating While Connected to a Free Account: If you are connected to a free account on your website, this error can occur. Please ensure that you are logged into the PRO account and reconnect your website. You can do this by navigating to Rank Math SEO → Dashboard → Help, disconnecting your account, and then reconnecting it with the correct PRO account.


-
Not Enough Storage Space: If your web server does not have enough storage capacity, it may also lead to this error. Check if you can upload other files to your website. If not, consider freeing up some space or contacting your web host for more storage.
If you continue to experience issues after trying these steps, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further. Thank you for raising this concern!

Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
We can see that you purchased the Content AI Starter plan. Please note that Content AI plans differ from our Rank Math PRO subscription. If you intend to purchase the PRO plugin, please purchase it here: https://rankmath.com/pricing/
Let us know if you want to ask for a refund on your Content plan so you can purchase the PRO plugin instead.
We really look forward to hearing back from you. Thank you.
Why is my account showing as free and not pro when i check my rankmath dashboard on your website??
Hello,
We checked your account and we can see that the subscription has expired four days ago and we do not have any option to revert a subscription that has expired already. You will have to make a new purchase:

Hope that helps.
Hi,
Can you please cancel the AI plan and shift my plugin to PRO?
Awaiting quick response.
Hello,
Those are two distinct subscriptions so we cannot switch one for the other.
Having said that, you can cancel the Content AI subscription by following this guide: https://rankmath.com/kb/cancel-subscription/
To get access to the PRO subscription you would need to purchase a new one from here: https://rankmath.com/pricing
Thank you.
