Hello, we’re sorry to hear that you’re encountering issues while trying to update your WordPress plugin to the beta version. The error message you’re seeing, “PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature,” usually occurs due to one of the following reasons:
- There’s an issue with the zip file you’re uploading.
- You try to update the PRO version while connected to the free account on your website.
- WordPress doesn’t have enough memory on a web server to unzip and upload the zip file contents.
- If your server is located in a sanctioned country, your requests will be blocked by our server, and you will see the above error.
To resolve this issue, please ensure that you are following the correct steps for updating to the beta version. If you are still encountering issues, please feel free to reach out to our support team directly from here, and our support expert will be more than happy to help you out.

Hello,
To fix this issue, you’ll have to reconnect your Rank Math account on your website. To do that, navigate to your WordPress admin area > Rank Math > Dashboard > Help, disconnect and reconnect your Rank Math account.
