I just install droplet for Wordpress (follow: https://www.digitalocean.com/community/articles/one-click-install-wordpress-on-ubuntu-12-10-with-digitalocean)
Then add more site to the droplet (follow: https://www.digitalocean.com/community/articles/how-to-set-up-multiple-wordpress-sites-on-a-single-ubuntu-vps)
Everything work well when I go to bed last night. But, this morning, I got "Error establishing a database connection" for all of sites.
I don't know why, but I try Power Cycle the droplet, and everything go well. I think that's all, but this evening, I met that problem again.
Hope you can help me. My main site is: http://bloggeritems.com/
