- Log in to Plesk.
- In the left sidebar, click Websites & Domains:
- In options panel at the far right, click the PHP Selector icon. If the PHP Selector icon does not appear in the options panel at the far right, your server does not use CageFS. Please see the Switching PHP versions without CageFS section below.

On the next page, select the desired version of PHP from the PHP Version list box and then click the Set as a current button.
