Hello,
We apologize for the issue you are facing with updating Rank Math Pro. The error message you are encountering, PCLZIP_ERR_BAD_FORMAT (-10), typically indicates that there is a problem with the zip file being used for the installation or update. Here are a few steps you can take to resolve this issue:
-
Clear Cache: Clear your browser cache and any caching plugins on your WordPress site.
-
Re-download the Plugin: Go to your Rank Math account and re-download the latest version of the Rank Math Pro plugin. Sometimes, the downloaded file may be corrupted.
-
Manual Installation: If the automatic update fails, you can manually install the plugin:
- Deactivate and delete the existing Rank Math Pro plugin from your WordPress dashboard.
- Upload the new zip file you downloaded via Plugins → Add New → Upload Plugin.
-
Check File Permissions: Ensure that your server has the correct file permissions set for the wp-content directory and its subdirectories.
-
Contact Hosting Provider: If the issue persists, it might be worth contacting your hosting provider to ensure there are no server-side issues affecting the installation.

Where can I download Pro version please?
Hello,
Thank you for contacting us, and sorry for any inconvenience that might have been caused.
You do not have a Rank Math PRO subscription on your account. The reason for the error is that you are trying to update the PRO version of the plugin while connected to your free account.

Please purchase a new subscription here to continue using the PRO plugin: https://rankmath.com/pricing/
Alternatively, you can deactivate the PRO plugin if you do not want to continue with the PRO subscription.
Hope this helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you for choosing Rank Math.
I don’t understand because it says PRO license in my dashboard.
Hello,
You once had the PRO license, which was cancelled and not renewed. That PRO subscription ended on August 1, 2025.
It is possible you still have the plugin installed on your website, and for you to keep using the PRO plugin, you’ll need to purchase a PRO subscription.
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
