Internal 500 and can't login

if you go to our site we get

# This page isn’t working is currently unable to handle this request.


Upon refresh everything comes up but we can’t login, nothing happens.

We have php 7.2 and NC 14 on lightspeed server
Its a dedicated server but its managed so we don’t have console.

Any help would be appreciated.

I checked error logs and there is nothing in them…
