Installation failed: Error establishing a database connection This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at sql100.byetcluster.com could not be established. This could mean your host’s database server is down. Are you sure you have the correct username and password? Are you sure you have typed the correct hostname? Are you sure the database server is running? If you are unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress support forums.
Other Information
this happens so often. When I try to enter my site, sometimes it shows ‘Database is down’, I didn’t make so much changes in my site, but after my account disabled temporarily for 1 day, this keeps annoying me.
actually, it comes out when there are no entries for 1 or 2 days to the site. When i want to install something, it pops out.
And according to pagespeed test, my speed index was 0.7s, but after temporary blocking for 1 day, it increased to 3.7s. I don’t know why. Before temporary blocking, my site was working fine.
