Update Failed

Hello,

I’m sorry to hear that you’re experiencing issues with updating Rank Math SEO. The error message “PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature” usually occurs due to a few reasons, such as a corrupted 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’s contents.

To resolve this issue, you can try the following steps:

1. Ensure that you are updating the PRO version while connected to the correct account. You can disconnect your account by navigating to Rank Math SEO → Dashboard → Help and then reconnect it by clicking on Connect Now.

2. If you continue to experience the same error, it might be due to insufficient storage space on your web server. In this case, you can try deleting some files from your web server or contact your web host to request more storage space.

If you have multiple Rank Math accounts (free account, PRO account), we recommend opening a support ticket to get your Rank Math accounts merged to avoid this issue in the future.

You can open a support ticket directly from here, and our support expert will be more than happy to help you out.

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