The error message you're encountering, "Apache Passenger is required by Node.js Selector," suggests that your hosting environment requires the Apache Passenger module to be installed and enabled in order to use the Node.js Selector feature in cPanel.

Here are steps you can take to address this issue:

1. Contact Your Hosting Provider:

   • Start by getting in touch with your hosting provider. They should be able to assist you in enabling Apache Passenger for Node.js Selector or provide guidance on how to set it up.

2. Check cPanel Configuration:

   • If you have access to your cPanel settings, look for an option to enable or configure Apache Passenger. It might be listed under a section related to server modules or extensions.

3. Install Apache Passenger:

   • If Apache Passenger is not installed on your server, you'll need to install it. This can typically be done through your hosting provider's control panel or by contacting their support for assistance.

4. Verify Node.js Installation:

   • After ensuring Apache Passenger is installed, verify that Node.js is also properly installed and configured on your server. Use the node -v command via SSH to check the Node.js version.

5. Review Hosting Documentation:

   • Refer to the documentation provided by your hosting provider. They may have specific instructions or requirements for running Node.js applications with cPanel and Apache Passenger.

6. Consider a Different Hosting Provider:

   • If your current hosting provider doesn't support the required configurations and you need Node.js for your application, you might need to consider switching to a different hosting provider that offers the necessary support.

Remember, the exact steps and options may vary depending on your hosting provider and the specific configuration of your server. If you're not comfortable making these changes yourself, don't hesitate to reach out to your hosting provider's support team for assistance. They should be able to guide you through the process or make the necessary adjustments on your behalf.
