Once you have updated your WordPress file, you should be able to access your site normally. If you are still seeing the “Establishing a Database Connection Error,” it is possible that your host has placed restrictions on your account which are preventing WordPress from communicating with the database.

In order to fix this, you’ll need to troubleshoot the problem to determine what is causing it.

Step 1: Check Your Database Credentials

If you’re receiving a ” WordPress database connection error” it means that either your WordPress files are unable to communicate with your database or your database credentials (username, password, hostname, or port) are incorrect. To check if your credentials are the issue: Log into your cPanel and click on phpMyAdmin. In the left-hand column of phpMyAdmin, you should see a list of databases. If you don’t see any databases listed, this is likely the cause of the problem. To check if your username and password are entered correctly: In the same left-hand column of phpMyAdmin, click on the database name you saw in Step 1. A new page will load with a list of tables inside that database. At the top of this page, there is a set of text boxes for username, password, hostname, and port. Make sure that these fields match the information from your wp-config file. The most common mistake here is entering localhost in the hostname field when it should be .

Step 2: Find the Corrupted Database Tables

If your WordPress site is showing the “Establishing a database connection” error, it means that something is wrong with the connection between your website and the database. This can be caused by a number of things, but the most common cause is an incorrect database login credentials in your wp-config.php file. The first thing you should do is check your wp-config.php file for any errors. If you see any typos or incorrect information, correct them and save the file. If that doesn’t fix the issue, try resetting your database password. If neither of those solutions work, it’s likely that your database is corrupt. To fix this, you can use a tool like phpMyAdmin to repair your database tables. Once you’ve repaired your database tables, try accessing your site again. If it still doesn’t work, contact your host and they may be able to help you further troubleshoot the issue.

Step 3: Add My Site to the “Allowed Hosts” List in Your Database Configuration file

If you’re running WordPress on a shared host, chances are you’ll need to add your site to the “Allowed Hosts” list in your database configuration file. This is because many hosts have strict security rules that prevent WordPress from connecting to the database unless the site is explicitly allowed. To do this, open your wp-config.php file and look for the following line: /** MySQL hostname */ define(‘DB_HOST’, ‘localhost’); Replace ‘localhost’ with your actual hostname (you can find this in your control panel or documentation). Save the file and upload it back to your server.

Step 4: Optimize the Database Connections and Increase PHP Memory Limit

Once you have troubleshooted the problem and found that it is not caused by a corrupt database or erratic server behavior, it is likely that your WordPress site is having difficulty connecting to your database due to high traffic or an unstable plugin. In this case, you will need to optimize your database connections and/or increase your PHP memory limit. To do this, you will need to edit your wp-config.php file and add the following lines of code: define(‘WP_MEMORY_LIMIT’, ‘512M’); define(‘WP_MAX_MEMORY_LIMIT’, ‘1024M’); This will increase the memory limit for WordPress and should help stabilize the connection to your database. If this does not solve the problem, you may need to speak with your host about further optimizing your server for WordPress.

Step 5:Contact your Hosting Provider

If you are still seeing the “Error establishing a database connection” message, it’s likely that your WordPress hosting provider is the cause of the problem. The first thing you should do is contact your hosting provider and let them know about the issue. They may be able to help you fix the problem or at least point you in the right direction.
