Hi I am using droplet with 1Gb memory and installed 18 domains and wordpress on it. The domains are fresh and no traffic yet. I found “error establishing a database connection” for all domains today. I don’t know the best solutions because I just new user here. Can someone tell me the reasons of my problem? Now I just upgrade droplet to 2GB memory and works fine. But I still want to know what the reasons, is 18 fresh domains with no traffic too many for 1GB droplet?
