Error Establishing a Database Connection in WordPress

1. Inaccurate database data

The database facilitates data organization, retrieval, and storage. When someone visits the website, it connects to the database automatically. However, when the site is unable to access the WordPress database due to incorrect login credentials provided, a database connection error appears in the WordPress website.

2. WordPress Files That Have Been Corrupted

Steps to Resolve the Problems Causing “WordPress Error Establishing a Database Connection”

The steps outlined below will assist you in resolving database connection issues. Before you begin troubleshooting the error, you should make a backup of your WordPress site to be safe.

1. Get the Database Information Correct

As previously stated, the most common cause of this error is incorrect database login information. Your login credentials may have changed as a result of moving your website to a new web host.

The wp-config.php configuration file stores the credentials for your WordPress database. This file is stored in the WordPress website’s root. All of your database data and essential settings are stored in this WordPress file. Database information in the configuration file, such as database name, password, username, and host details, should be correct. If not, edit the configuration file and replace the old credentials with the new ones to fix the problem.

Connect to your website via SFTP and navigate to the root directory to find the configuration file. On cPanel, you can also edit the file by going to the root directory.

2. Troubleshoot WordPress Files

A corrupted file can be caused by a failed WordPress plugin, theme, or software update. You can connect to your site via FTP and navigate to the root directory to resolve any plugin-related issues.

Choose “wp-content”.  Another folder called plugins can be found inside the wp-content folder. This is where WordPress saves all of the plugins you’ve installed on your website. Choose that and rename it to anything else you want.

Finally, return to your WordPress site to see if the problem is still present. If the error was caused by a plugin problem, the site will not display the error message.

If you’re still getting the “error establishing a database connection in WordPress” message, look for any problems in the theme files. You can try reinstalling the theme files to see if that helps.

To fix the problem, use FTP to connect to your WordPress site and navigate to the WordPress root directory, as mentioned earlier. You can now save the “wp-config.php” configuration file to your desktop from there.
