I want to set default php handler is apache_module. (if I add new vhosts, that php handler should be apache_module) or How can disable fcgid, run phps only apache_module?
Just define it in Hosting Parameters of your Service Plan. All new subscriptions based on this Service Plan will be created with this defined PHP setting.
If you have Power User mode with enabled Custom View Settings, you can define PHP handler in Server -> Custom View Settings -> Hosting Parameters -> Run PHP as.
