"On CentOS 6 x64, changing the PHP version caused a change of PHP handler to FastCGI by Apache. ."
- Plesk Onyx 17.5.3 23 March 2017 (Linux)
PHP handler is automatically getting changed after changing PHP version in Plesk > Domains > example.com > PHP Settings . Even if the other option FPM application served by nginx is available in drop down section of run PHP as under PHP settings .
Thhis is Plesk bug #PPPM-5618 which was fixed in Plesk Onyx 17.5.3 .
Upgrade to the latest Plesk version .
As a workaround, change PHP handler of domains manually at Plesk > Subscriptions > example.com > Websites & Domains > PHP Settings .
