If you're experiencing issues with the PHP selector not displaying PHP handler versions, it could be due to a few different reasons. Here are some steps you can take to troubleshoot and potentially resolve the issue:

1. Check Server Configuration:

   • Make sure your server is properly configured to use a PHP selector. Some web hosts or server environments may not have this feature enabled.

2. Verify PHP Selector Installation:

   • Ensure that the PHP selector is properly installed on your server. If you're using a hosting provider, contact their support team to confirm.

3. Correct PHP Handler Configuration:

   • Verify that the PHP handler (e.g., mod_php, FastCGI, PHP-FPM) is installed and properly configured on your server. If not, install and configure the appropriate PHP handler.

4. Check PHP Versions Installed:

   • Ensure that you have multiple PHP versions installed on your server. The PHP selector relies on having multiple versions to choose from.

5. Permissions and Ownership:

   • Make sure that the PHP selector has the necessary permissions to access and manage PHP versions. It should have the appropriate privileges to modify the PHP configurations.

6. Control Panel Issues:

   • If you're using a control panel like cPanel or Plesk, check if there are any known issues with the PHP selector in your specific version of the control panel. You might need to update or reconfigure the control panel.

7. Restart Services:

   • After making any changes to PHP configurations or installations, it's important to restart your web server (e.g., Apache, Nginx) and PHP services to apply the changes.

8. Check Error Logs:

   • Look for any error messages or logs related to the PHP selector. This can provide valuable information about what might be causing the issue.

9. Contact Hosting Provider or System Administrator:

   • If you've tried the above steps and still can't get the PHP selector to work, it's advisable to contact your hosting provider or system administrator for further assistance. They may have specific knowledge about your server environment and can help troubleshoot the issue.

Remember that the specific steps to resolve this issue may vary depending on your hosting environment and the control panel you're using. If possible, refer to the documentation provided by your hosting provider or control panel for guidance on configuring the PHP selector.
