Unable to update PRO Version

Hello,

I’m sorry to hear that you are facing the “PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature” error while trying to update the Rank Math PRO version. This error usually occurs due to a few reasons, such as issues with the zip file, being connected to the free account, or not having enough memory on the webserver.

To resolve this issue, you can follow these steps:

1. Check Zip File: Ensure there’s no issue with the zip file you’re uploading. You can download the latest Rank Math PRO version from your account and install it on your website.

2. Update PRO Version: If you are connected to the free account, disconnect your account by navigating to Rank Math SEO → Dashboard → Help and then reconnect it to the correct PRO account. Follow the steps mentioned in this guide to reconnect your account correctly.

3. Storage Space: If the error persists, check if your web server has enough storage capacity for WordPress to unzip and upload the file’s contents. You may need to free up space or contact your web host for assistance.

If you continue to face issues after following these steps, please feel free to reach out to our support team for further assistance.

Thank you for bringing this to our attention, and we appreciate your patience as we work to resolve this issue for you.

Have a great day!
