Failed to install PHP FPM 8.0 - Failed to start php-fpm80.service

Hello friends,

I am using CWPpro version: 0.9.8.1120.
I try to install PHP FPM 8.0 via menu PHP-FPM Selector  and Start compiler button, but failed after some hours.

• In next day I get email from MONIT,
• email subject: monit alert -- Execution failed php-fpm80
• email content: Description: failed to start (exit status 5) -- '/usr/bin/systemctl start php-fpm80.service': Failed to start php-fpm80.service: Unit not found.

Anyone know how to solve this?

Thank you very much.
