If you're experiencing issues with the "Hide Alt-PHP versions from cPanel's MultiPHP Manager" option in CloudLinux, here are some troubleshooting steps you can take:

1. Verify Licensing and Configuration:

   • Ensure that your CloudLinux server has a valid license and that it's properly configured. Licensing issues can sometimes lead to unexpected behavior.

2. Check cPanel's, MultiPHP Manager:

   • Confirm that you're accessing the MultiPHP Manager from within cPanel. The option to hide Alt-PHP versions is specific to cPanel's MultiPHP Manager and may not apply to other interfaces.

3. Confirm CloudLinux and cPanel Versions:

   • Make sure you're running the latest versions of both CloudLinux and cPanel. Compatibility issues can arise if you're using outdated software.

4. Clear Browser Cache:

5. Ensure Correct Permissions:

   • Verify that the user account you're using to access cPanel has the necessary permissions to manage PHP versions and settings.

6. Check for Conflicting Plugins or Extensions:

   • If you have any third-party plugins or extensions installed on cPanel, try temporarily disabling them to see if they might be causing conflicts.

7. Review CloudLinux Documentation:

   • Consult the official CloudLinux documentation or knowledge base for any specific instructions or troubleshooting steps related to hiding Alt-PHP versions.

8. Contact Support:

   • If none of the above steps resolve the issue, consider reaching out to CloudLinux support. They can provide specific guidance and assist in troubleshooting the problem.

9. Verify License Type:

   • Ensure that you have a CloudLinux license that includes the feature to hide Alt-PHP versions. Different license types may have different feature sets.

10. Check for Updates:

    • Regularly check for updates to CloudLinux and cPanel, as new versions may include bug fixes and improvements that address issues like this.

If after following these steps you're still experiencing issues, it's recommended to contact CloudLinux support for further assistance. They will have access to specific logs and diagnostics that can help identify and resolve the problem.
