Hello,
I’m sorry to hear that you are facing issues updating the Rank Math PRO version 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 zip file contents.
To resolve this issue, you can follow these steps:
-
Check Zip File: Ensure there is no issue with the zip file you are uploading. You can download the latest Rank Math PRO version from your account and install it on your website.
-
Update PRO Version Correctly: If you are updating the PRO version while connected to the free account, make sure to confirm the email address connected to your website from Rank Math’s account page. Disconnect your account from Rank Math SEO → Dashboard → Help and reconnect it by following the steps mentioned in the knowledgebase article.
-
Not Enough Storage Space: If the error persists, it might be due to insufficient storage space on your web server. Check if you can upload other files to your website. If storage space is the issue, consider deleting unnecessary files or contacting your web host for more storage.
If you have multiple Rank Math accounts (free account, PRO account), and you need further assistance, please open a support ticket to get your accounts merged to avoid this issue in the future.
