Update mislukt: Het pakket kon niet worden geïnstalleerd. PCLZIP_ERR_BAD_FORMAT

Hello,

We apologize for the issue you are facing with the installation error: PCLZIP_ERR_BAD_FORMAT. This error typically occurs when there is a problem with the zip file you are trying to install, or it could be related to your server’s PHP configuration.

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

1. Check the Zip File: Ensure that the zip file you are trying to upload is not corrupted. You can try downloading the Rank Math plugin again from the official website to ensure you have a valid file.

2. Increase Upload Limit: Sometimes, this error can occur if your PHP settings restrict large uploads. You may need to increase the upload limit in your PHP configuration. If you’re using cPanel, you can do this by navigating to the MultiPHP INI Editor and adjusting the upload_max_filesize and post_max_size settings.

3. Install via FTP: If the above steps do not work, consider installing the plugin via FTP. You can follow the instructions in this guide on installing Rank Math using FTP.

4. Check PHP Version: Ensure that your server is running a supported version of PHP (7.4 or greater). You can check and upgrade your PHP version through cPanel or by contacting your hosting provider.

If you continue to experience issues, please reply to this ticket with any additional details or errors you encounter, and a human agent from our support team will assist you further.

Thank you for raising this concern!
