PCLZIP_ERR_BAD_FORMAT (-10): Unable to find End of Central Dir Record signature

Hello,

We apologize for the issue you are facing with the plugin update. The error message PCLZIP_ERR_BAD_FORMAT (-10) typically indicates a problem with the zip file that is being used for the update, which may be corrupted or not properly formatted.

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

1. Clear Cache: If you are using any caching plugins, clear the cache and try updating again.

2. Manual Update: You can manually update the plugin by downloading the latest version from your Rank Math account and uploading it via the WordPress admin area. Here’s how:

   • Go to Plugins > Add New.
   • Click on Upload Plugin and select the downloaded zip file.
   • Click Install Now and then activate the plugin.

3. 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 applied.

4. Check for Conflicts: There might be a conflict with another plugin or theme. You can try deactivating other plugins temporarily to see if that resolves the issue.

If these steps do not resolve the problem, please reply to this ticket with your site URL, and a human agent from our support team will assist you further. Thank you for your patience!
