Hello,
We apologize for the issue you are facing with the Rank Math PRO update. The error message you are encountering, PCLZIP_ERR_BAD_FORMAT (-10)
, typically indicates a problem with the zip file being corrupted or not properly formatted.
Here are a few steps you can take to resolve this issue:
- Check Your PHP Version: Ensure that your server is running a supported version of PHP, as Rank Math requires a stable version to function correctly. You can refer to our guide on upgrading your PHP version for assistance.
- Manual Update: If the automatic update fails, you can manually download the latest version of Rank Math PRO from your Rank Math account and upload it via FTP or your hosting control panel.
- Clear Cache: Sometimes, caching plugins can interfere with updates. Clear your site cache and try updating again.
- Check File Permissions: Ensure that your WordPress installation has the correct file permissions to allow updates.
If these steps do not resolve the issue, 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!
