My WordPress site was working fine until the last few hours. But now, it is showing the “Error Establishing a Database Connection” error. The image of the error is attached below
Can anyone tell me how to fix this problem and make my site running again?
There are several reasons for the error establishing a database connection error. Below are some of them.
- Your database server is running out of resources
- The database connection with your wp-config.php file has some errors (for example a mistyped database name, or database user name, or database password)
- Your database is corrupted (the chances are very small)
The first thing I would recommend you to do is immediately contacting your hosting provider and ask them for a solution. In most of the cases, they will resolve the issue within a matter of minutes.
If you can’t reach them for any reason, here are some of the tips you could follow.
- Make sure that your server is not overwhelmed and running out of resources. You can do this by visiting your hosting account.
- Check the wp-config.php in the WordPress installation directory and compared the database name, database username, and the database password. Make sure that they are entered correctly.
- Repair your WordPress database either from the database manager in your cPanel or hosting account, or by adding define ( ‘WP_ALLOW_REPAIR’ , true); to the wp-config.php. If you use this code, when you try to access your website’s backend, a database repair screen will open up (I do not recommend this unless you tried every other method to fix the issue.
Hope you fix the problem.
