Hello,
We apologize for the issue you are facing with the plugin update. The error message you are encountering, "PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature", typically indicates that there is a problem with the zip file being used for the update. This can happen due to a corrupted download or an issue with the server.
Here are a few steps you can take to resolve this issue:
- Clear Cache: Clear your browser and site cache to ensure that you’re not loading a cached version of the plugin.
- Manual Update: You can try manually updating the plugin by downloading the latest version from the Rank Math website and then uploading it via your WordPress dashboard under Plugins → Add New → Upload Plugin.
- Check File Permissions: Ensure that your server has the correct file permissions set for the WordPress directories, especially for the
wp-content folder.
- Check PHP Version: Make sure your server is running a supported version of PHP (7.4 or greater). You can check this in your WordPress dashboard under Tools → Site Health → Info.
If these steps do not resolve the issue, please reply to this ticket with your site URL, and a human agent from our support team will assist you further. Thank you for raising this concern!
