Webriti Crashed Site and can’t fix

I was sent an email saying that my website has a critical error from Webriti Companion
plugin for the theme Dream Spa. I tried fixing it by updating. Now it says Webriti fails to load and I can’t get my homepage to show anything but the intro image and the News section which can only be viewed on my dashboard. When I go to my website when I’m not logged in it still shows my website as down and says ip address not found in chrome or insecure in mozilla with the maintenance page.
