Hello,
We apologize for the issue you are facing with updating your Rank Math Pro installations. The error message you are encountering, PCLZIP_ERR_BAD_FORMAT (-10), typically indicates that there is a problem with the zip file being used for the update. Here are a few steps you can take to resolve this issue:
-
Check for Corrupted Files: Ensure that the Rank Math Pro zip file you are trying to upload is not corrupted. You might want to download the latest version of the plugin again from your Rank Math account.
-
Manual Update: If the automatic update is failing, you can manually update the plugin. To do this, follow these steps:
- Download the latest version of Rank Math Pro from your account.
- Go to your WordPress dashboard and navigate to Plugins → Add New.
- Click on Upload Plugin and select the downloaded zip file.
- Click on Install Now and then activate the plugin once installed.
-
Check File Permissions: Ensure that your server has the correct file permissions set for the WordPress directories. Sometimes, incorrect permissions can prevent updates from being installed.
-
Update Other Plugins: Make sure all other plugins are updated as well, as conflicts with outdated plugins can sometimes cause issues during updates.
If these steps do not resolve the issue, please reply to this ticket with the URLs of your websites so that a human agent from our support team can assist you further. Thank you for raising this concern!
