Hello,
We apologize for the issue you are facing with upgrading your WordPress plugins. The error message you are encountering, "PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature," typically indicates a problem with the plugin’s zip file or the way it is being handled during the update process.
Here are a few steps you can try to resolve this issue:
-
Check PHP Version: Ensure that your site is running a supported version of PHP. You can check this by navigating to Tools → Site Health → Info in your WordPress dashboard and looking under the Server section for the PHP version.

-
Clear Cache: If you are using any caching plugins, clear the cache and try updating again.
-
Manual Update: If the automatic update fails, you can manually update Rank Math by downloading the latest version from the Rank Math website and uploading it via the Plugins → Add New → Upload Plugin option in your WordPress dashboard.
-
Check File Permissions: Ensure that your WordPress installation has the correct file permissions. Sometimes incorrect permissions can prevent updates from being applied.
-
Reinstall Plugin: Since you’ve already tried reinstalling, ensure that you completely remove the existing plugin before uploading the new version manually.
If these steps do not resolve the issue, please reply to this ticket with your site URL so that a human agent from our support team can assist you further. Thank you for raising this concern, and we hope to help you get this resolved soon!

Hello, whit php version is mendatory? Thanks
Hello,
Rank Math requires PHP 7.4 or greater. However, the account you used to open this ticket only has a Content AI subscription, not any Rank Math PRO subscription.
Please note that in order to update the PRO plugin, you’ll need an active Rank Math PRO subscription.
However, if you have an active Rank Math PRO subscription with some other email address, please share that with us so that we can locate your account.
Looking forward to helping you.
Thank you.
