As a business owner, few things are more panic-inducing than visiting your website only to see the message “Error Establishing a Database Connection.”
Unless your developer told you otherwise, you likely hadn’t even considered the possibility that your website was connected to a database, making it double concerning.
Whatever the case, should you find yourself staring at this ominous greeting, fear not: all it means is that you’re locked out of both your website and dashboard.
And having gotten my hands dirty fixing hundreds of WordPress websites over the years, it’s a fairly quick and easy fix.
In this post, we’ll explore how to fix the “Error Establishing a Database Connection” issue in WordPress by verifying our database info, ensuring your server is up and running, and confirming we have access to our data storage.
Let’s get started on solving this together.
Key Takeaways
- Check your wp-config.php file first. Ensure the database name, user, password, and host are correct.
- If that doesn’t work, see if your web server or MySQL is down. You might need to reboot servers or talk to your hosting company.
- Try repairing the WordPress database by adding code to the wp-config.php file.
- Use a PHP script to test if your WordPress site can connect to its database correctly.
- Update your WordPress site URL in phpMyAdmin if needed, and check user permissions there.
Understanding the Error
When WordPress displays the message “Error establishing a database connection,” your website can’t connect to the database that stores essential information.
This error usually occurs due to incorrect database login credentials or when the server is unresponsive.
The ‘Error establishing a database connection’ in WordPress
Seeing the “Error establishing a database connection” message on my WordPress site always worries me.
It means my website can’t reach its database. This isn’t good because all my site’s content and settings live in that database.
If WordPress can’t connect, nobody can see my website.
I’ve faced this error more times than I’d like to admit since starting with WordPress in 2010.
Usually, it happens when something’s off with the database details in the wp-config.php file or if there’s a problem at the hosting provider’s end.
I check those areas first: ensuring the database name, user, password, and host are correct and seeing if the server is running well.
Fixing ‘Error establishing a database connection’ starts with checking simple things: your wp-config.php file and hosting server status.
Troubleshooting Steps
When your WordPress site encounters the dreaded “Error establishing a database connection,” it can be unsettling.
However, there are effective troubleshooting steps that could quickly resolve this issue and get your website back up and running smoothly.
Read on to discover these practical solutions.

Check database credentials in wp-config.php file
I often start with the wp-config.php file to fix a database error. This file has important info like the database name, user, password, and server. You must get these right. If they’re wrong, your site can’t connect to its database.
Here’s what I do: I open wp-config.php with an editor. Then, I check DB_NAME, DB_USER, DB_PASSWORD, and DB_HOST values. These have to match exactly what your web host gave you. Many times, fixing just this solves the problem.
Verify database host information
It’s crucial to check the database host details in WordPress. Most hosts use localhost, but some have different settings.
This means the place where your website’s data lives might not always be “localhost.” So, I make sure to talk with my hosting company.
They tell me exactly what to write for the database host in my wp-config.php file.
Always confirm your database host info to avoid connection errors.
I also open the wp-config.php file through a file manager or FTP client. This step is key because it links my site to its data. When typing the host info, accuracy matters a lot. One mistake and your website won’t connect to its database.
Repair the database
When I encounter the ‘Error establishing a database connection’ in WordPress, there are specific troubleshooting steps that can be taken. The third essential step is to repair the database.
This involves accessing the wp-config.php file and adding ‘define(‘WP_ALLOW_REPAIR’, true);’. Subsequently, navigate to http://www.yoursite.com/wp-admin/maint/repair.php to access repair settings and remove the repair code upon completion.
Repairing the database ensures stability and functionality. It’s a key component of restoring a smooth user experience for visitors while managing my website efficiently….
Check MySQL server status
I always ensure that the MySQL server is up and running to keep things smooth. I monitor its status regularly, especially during busy times, and shared hosting can sometimes lead to performance issues or errors.
Whenever such concerns pop up, I reach out to the hosting provider for a quick check on server responsiveness. It’s also helpful to take a peek at other websites hosted on the same server—it often gives valuable insights.
You see, when the MySQL server goes down due to heavy traffic, it can cause disturbances in connecting with the database. Shared hosting environments are prone to slower operations or malfunctions compared to dedicated ones because they share resources among numerous sites simultaneously.
Consequently, reaching out to your hosting provider for guidance proves beneficial—after all, nobody wants their website offline due to avoidable issues.
Check database user permissions
To fix a database connection error, I’d make sure the database user has sufficient permissions.
This is very important for accessing and making changes to the database. You can do this by verifying the permissions in phpMyAdmin.
If you find that the permissions are not enough, you should investigate further to ensure they’re adequate for the database user.
Test database connection with PHP script
Now, let’s move on to testing the database connection using PHP script. I need to create a file called testconnection.php and put the connection code in it. Then, I’ll replace ‘username’ and ‘password’ with my actual credentials.
After that, I’ll upload the file and access it via a web browser. This will confirm if my database user permissions are correct or not.
I found that creating the testconnection.php file wasn’t too difficult after understanding how it works.
By doing this, now I’m sure that the connection between my WordPress site and its database is functioning properly!
Update WordPress site URL
Updating the WordPress site URL is crucial for website functionality. It can be done using phpMyAdmin or by executing an SQL query to adjust the table name if the prefix was changed.
Using phpMyAdmin, you need to navigate to your database and find the wp_options table. Look for two entries, siteurl and home, ensuring they reflect your new URL. If not, change them accordingly.
If we decide on running an SQL query instead, this code will do it: “UPDATE wp_options SET option_value=’YOUR_SITE_URL’ WHERE option_name=’siteurl’.” Replace ‘YOUR_SITE_URL’ with your actual URL and adjust table names as needed.
Reboot web servers
When web servers encounter issues, restarting can resolve temporary glitches. For dedicated, local, and VPS servers, the restart process varies.
Restarting web servers might help to restore connectivity and eliminate malfunctions. When I had an issue before where my web server wouldn’t connect correctly, a quick restart resolved it.
Keep in mind that this should be one of the first steps you take before seeking support from your hosting company or WordPress developers – it’s simple but surprisingly effective.
Contact web hosting company for support
When the steps provided fail to resolve the error, it’s essential to reach out for assistance from the web hosting company. Most hosting providers offer troubleshooting help and support for connection issues.
In cases where further expertise is needed, hiring WordPress developers or seeking WPBeginner Pro Services can provide additional help in resolving this issue.

Update WordPress site URL using phpMyAdmin
To fix URL-related issues in WordPress, I navigate to phpMyAdmin and choose the WordPress database. Then, I run an SQL query to update the site URL. If needed, I modify the table name and replace the site URL as required.
This process is effective for correcting problems related to URLs on a WordPress site.
Reboot web servers for dedicated, local, and VPS
Now, let’s reboot the web servers for dedicated, local, and VPS. Rebooting varies depending on the server type. It might solve persistent connection errors or temporary glitches. If you need help, contact your hosting provider.
As a developer since 2010, I’ve helped numerous businesses with WordPress success. The reboot process can differ based on the server you’re using—an easy fix for some common issues that may arise—helpful when experiencing connectivity problems.

Most importantly, they can offer personalized support, ensuring that your website’s backend is thoughtfully reviewed and optimized for seamless performance. Moreover, reliable developers provide valuable support services such as SEO enhancements, hacked site repairs, and more to reveal the potential of a functional WordPress site.
