Updated as described for plan and for the subscription but didn't work. Had to manually configure on IIS Manager > FastCGI Settings
Hasan Gürsoy in case subscription is in "lock" status it remains unsynced with service plan. Also, if "hosting management" permissions is granted changes from the service plan are not propagated to the subscription.
We do recommend changing this setting directly under subscription, since manual changes under IIS might be overwritten since configuration managed by Plesk.
