The following steps will show you how to enable FPM or FastCGI for PHP execution in Plesk. Please note that we strongly recommend using FPM mode.
- Login to Plesk
- Under Websites & Domains, choose the domain you are encountering this issue with
- Choose the PHP Settings button
- Change the option to "run PHP as" to Apache + FPM
Now PHP will be in FPM mode. You may alternatively select Apache + FastCGI mode, however FPM mode is the better choice.
Tip: most web apps will not work with Nginx + FPM mode as that mode will not read any .htaccess files, which are typically required for most web apps to work.
