Hello,
I’m sorry to hear that you are facing issues updating the plugin and encountering 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:
- There might be an issue with the zip file you are trying to upload.
- You could be trying to update the PRO version while connected to the free account on your website.
- Your web server might not have enough memory to unzip and upload the zip file contents.
- If your server is located in a sanctioned country, your requests might be blocked.
To resolve this issue, you can follow these steps:
-
Check Zip File: Ensure that the plugin zip file is not corrupted. You can download the latest Rank Math PRO version from your account and install it on your website.
-
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 by following the steps mentioned in this guide.
-
Storage Space: If the error persists, check if your web server has enough storage capacity. You may need to delete some files or contact your web host for more storage space.
If you need further assistance, please feel free to reach out to our support team. Thank you for bringing this to our attention!
