Hello,
We apologize for the issue you are facing while trying to update the plugin. The error message you are encountering, PCLZIP_ERR_BAD_FORMAT (-10), typically indicates that the zip file of the plugin is corrupted or not properly formatted.
Here are a few steps you can take to resolve this issue:
-
Re-download the Plugin: Go to the official Rank Math website and download the latest version of the plugin again. Ensure that the download completes successfully without interruptions.
-
Manual Installation: If the automatic update continues to fail, you can manually install the plugin using FTP or SSH. Here’s a guide on how to do that:
-
Clear Cache: Sometimes, caching issues can cause problems during updates. Clear your website cache and any server-side cache if applicable.
-
Check File Permissions: Ensure that your WordPress installation has the correct file permissions to allow updates.
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,
It seems like you purchased the plugin with some other email address because we can only see the Content AI Creator subscription on your account.
Can you please share the email address which you used to purchase the plugin or you can search and forward the receipt from FastSpring.com so we can locate your account?
Back to your issue, one possible reason for this error is trying to update the PRO version of the plugin while connected to your free account.

I usually update the free first.
