Update failed: The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) :

Hello,

We apologize for the issue you are facing with the update and the redirection tool. 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. This can happen if the file is corrupted or not properly downloaded.

Here are a few steps you can take to resolve this issue:

1. Manual Update: You can manually update the Rank Math plugin by downloading the latest version from the Rank Math website and then uploading it via your WordPress dashboard under Plugins > Add New > Upload Plugin.
2. Check File Permissions: Ensure that your server has the correct file permissions set for the WordPress directories, especially for the wp-content folder.
3. Deactivate Other Plugins: Sometimes, conflicts with other plugins can cause issues. Try deactivating other plugins temporarily to see if that resolves the problem.
4. Check Server Resources: Ensure that your server has enough resources (like memory) to handle the update process.

Regarding the redirection tool not working, it could be related to the same issue or a separate configuration problem. If you continue to experience issues, please reply to this ticket with your site URL so we can assist you further.

Thank you for raising this concern!
