503 Service Unavailable

all of a sudden I take the following 503 Error. I haven't made any change the last month but now it's the second day that I receive the specific error everytime that I visit my site. It's CWP7 and I updated php to the last version but the error still exists.


Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

My problem have just resovled.
Obviously, the problem appears after updates. In order to fix this I switched php to latest version from PHP Version Switcher.
Then, I went to Select WebSevers sub-menu, click "Apache only" and uncheck " Force Apache to use PHP-FPM Selector, this will disable PHP Selector 2 and PHP Version Switcher."
Save and rebuild configuration and all things look good.
