Website database not working
I have a website hosted on my friend's account whose url is http://www.gamingalien.tk . I am using wordpress on that website and receiving an error message Error establishing a database connection. Even my friend's website hosted on the same account with wordpress is getting the same error message. So please help me fix this problem as soon as possible. I am even receiving some dns errors. Please fix these problems. My friend's website url is http://www.satyaakam.net . Both my and my friend's website are hosted on digital ocean only.
