How do I fix Error establishing a database connection in WordPress?

WordPress uses PHP requests to connect to the MySQL database, take the data it requires, and then present everything on the screen.

This is where the error occurs. The error occurs if, for whatever reason, WordPress cannot access the data in the database via PHP requests. When that issues, WordPress primarily doesn’t know what to do subsequent, so the only thing it can tell is, “Error establishing a database connection.” With that being said, there can be a few reasons why the error occurs. Some of the more common ones:

  • Wrong login credentials. WordPress requires a specific login and password to access the database. If those have evolved for any purpose then WordPress will no longer be capable to get anything from the database.
  • Corrupted WordPress files.The core WordPress files can go corrupted as a consequence of a crashed update, among others. This can involve things like abandoned updates of the plugins, themes, and even the central WordPress software updates.
  • Corrupted database This might be a consequence of a rogue plugin messing up the database within, a hacker’s initiative, a theme fault, and many more.
  • The database server is down.In some cases, the web server – the server that saves your website files – is run on a separate machine than the database. And that separate database server can really be down for whatever reason.
  • Too much traffic. Even though this is a sound as a good problem to possess, it’s still a problem. Specifically, your database might be unresponsive due to a huge inflorescence in traffic. For example, maybe one of your posts ran viral and now everyone and their dog attempts to access your site? Hence the server is not able to manage part of those visits.
