If you're not seeing the .cl.selector option for new users in Plesk, it's possible that there might be a configuration issue or a change in the way PHP versions are managed on your server. Here are steps you can take to troubleshoot and potentially resolve the issue:

1. Check for Updates: Ensure that your Plesk installation is up to date. Sometimes, new features and options are introduced in updates.

2. Verify PHP Selector Extension: Make sure that the "PHP Selector" extension is installed and active in your Plesk installation. You can do this by navigating to Extensions in the Plesk interface.

3. Verify Hosting Type: Confirm that the hosting type is set to "Website Hosting" rather than "Forwarding" or "No hosting". This setting can affect the availability of certain features.

4. Check User Role and Permissions: Ensure that the user you are creating or modifying has the necessary permissions to manage PHP settings. This can be checked and adjusted in the user's settings.

5. Switch to Service Provider View: Sometimes, certain features might be visible only in Service Provider view. Switch to this view by clicking on your username in the top-right corner and selecting "Switch to Service Provider View".

6. Check Server PHP Versions: Navigate to Tools & Settings > PHP Settings and confirm that you have multiple PHP versions installed on your server.

7. Customize Hosting Plans: In Plesk, hosting plans can restrict certain features. Ensure that the hosting plan associated with the user allows for PHP version selection.

8. Check for Customizations: If there have been any customizations or modifications made to the Plesk installation, they could potentially affect the visibility of certain options.

9. Contact Support: If none of the above steps resolve the issue, consider reaching out to Plesk support or your hosting provider for further assistance. They may have specific insights into your environment.

Keep in mind that Plesk interfaces and options might vary slightly depending on the version and configuration, so it's possible that there may be specific considerations for your setup.
