Upload Failed

Hello,

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

To address this issue, you can follow these steps:

1. Check Zip File: Ensure that the zip file you are uploading is not corrupted. 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 updating the PRO version while connected to the free account, make sure to confirm your email address in your Rank Math account and reconnect the website to the PRO account.

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

If you need further assistance or have any questions, please feel free to reach out to our support team directly here. Our experts will be happy to assist you.

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