Description of my issue

Since updating to Yunohost 11, I’m getting a Diagnosis error warning that php7.3-fpm is not running.

When I look at Services panel, it shows me this message: Service php7.3-fpm is dead :(

But the very next line in the Diagnosis shows me Service php7.4-fpm is running!

Is this just a minor unfinished element in the Diagnosis process that has not yet been tidied up before release of Yunohost 11?

Should I ignore the 7.3 warning? Or should I restart the 7.3 service and leave it running alongside php7.4-fpm?
