Hi,
This is the error i’m getting when i go to colorsandmirrors.000webhostapp.com/wp-admin - “Error establishing database connection”
Also, if go to colorsandmirrors.000webhostapp.com, the error i’m getting i’ve attached it as a screenshot. 
It was working fine till 30 mins back and suddenly when i was working in the admin panel when i was changing the content for the homepage, this happened.
How do i rectify this?
