My website is running in wordpress. It had been running acceptable for past 3 several weeks, but yesterday all of a sudden my website demonstrated me Error establishing a database connection

I didn't transformed anything during my site, things are OK, I approached my host and they've a foolish team of developers which have no idea to repair the mistake.

My website lost all traffic.

Help me to fix this issue.

Is it possible to connect with the database using another tool? For instance, many hosting that is shared services offer an installing of phpMyAdmin or similar, which might permit you to connect with the database and verify permissions, configurations, etc.

With no explicit error message, our capability to trobleshoot and fix is restricted.
