The problem, occurred today (probably a few hours ago), it says "Error establishing a database connection. I saw that topic in this forum but there was no answer which helps me to solve my problem.
Under CPanel–> MySQL Databases, my database is missing. Website’s all page are showing same “error establishing a database connection”, nor am I able to log in from wp-admin. I am also unable to log in at PhpMySQL.
Also, Under CPanel → Statistics, neither number of database is 0 nor 1, it is just missing.
This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at sql105 .byetcluster.com. This could mean your host’s database server is down.
Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums"
My problem is solved. But, another problem found on my website. That is when I open my link it is loading 1-2 sec on my front Home page and then automatically redirect to an existing link which I use in my website content but not in the redirect. It is on the content of my website. I can’t access my website properly. Please solve my problem @Admin.
