Since I value your time, I’m going to first recommend a path that’s the most likely to fix the problem for you quickly. Then, I’ll dig deeper and show you how to do all the fixes on your own manually.

Always keep a back-up:

Before you begin investigating the blunder, we generally prescribe taking a reinforcement or a back-up. A great deal of the suggestions underneath include controlling data in your database, so you would prefer not to compound the situation. You ought to dependably reinforcement before endeavoring to settle things on your WordPress site regardless of how technically knowledgeable you think you are.

When you have an effective reinforcement, it is an ideal opportunity to begin investigating your database association issues.

1- Check your Database Login credentials:

Wondering how your database login credentials could have suddently stopped working? Things like switching hosting companies. Or changing anything about your database name or user information could cause the error. If your wp-config file wasn’t updated to the new information. You may still have the wp-config file open from the last step. If not, log into your host’s cPanel and open the File Manager. Navigate to the directory where you installed WordPress, and look for a file called wp-config.php. Go ahead and open that for editing.

You’ll see the login credentials for your database, probably near the top of the file. It should look something like this:

As you can see, there are four pieces of information WordPress needs to access your database:

1. The name of the database (“DB_NAME”).
2. The login username (“DB_USER”).
3. The login password (“DB_PASSWORD”).
4. The database host (“DB_HOST”).

If anyone of these values is incorrect, WordPress will not be able to connect to the database. After clicking on your database name, you’ll see the principle screen populate with the names of the tables in your database.

To ensure this is the right database, you can locate the table named “wp_options”. And tap on the ‘Peruse” alternative alongside it. You should see your site’s name, URL, and your other general settings here. Presently you know regardless of whether you have the right database name in your wp-config record. In the event that it’s not right, simply ahead and settle it in wp-config.

Testing credentials:

Presently we should keep an eye on the username and secret word.

There are a couple of approaches to do this, some more tangled than others. I’ll give you both choices.

• You can either make a straightforward .php document to test whether you can interface with your database with the qualifications in your wp-config record.
• You can simply make another client and the secret phrase, and refresh your wp-config document with the new information. You’ll need to do this if #1 flops, so you may very well need to jump to this progression..

Username and password:

You must ensure that the username and password in your wp-config.php file match the values in the “MySQL Access” panel of your website’s application page on the Cloudways platform.

If the username and password do not match, open your wp-config.php file Edit it to include the values from the “MySQL Access” panel. That’s it! If you were attempting to do this via cPanel, you’d have to put in a lot more effort.

Now your database name, username, and password are all correct. That just leaves DB_HOST.

Database Host:

In most cases, this value will be “localhost,” but it depends on your host’s settings.

The last important value in WordPress wp-config.php file is DB_HOST. For most web hosting providers, this value needs to be localhost, which is the value in the file by default.

If you’ve carried out all the aforementioned steps, and you are still facing the problem. Then check this official WordPress list of DB_HOST values for various web hosting providers. Otherwise, you can contact your web hosting providers and ask them to provide you the DB_HOST value. You need to input into the wp-config.php file.

WordPress has a list of common hosts with their DB_HOST values on their website. If your host isn’t listed there, you can contact your hosting company to ask what value to use.

Repairing corrupt database:

In some cases, it could be that your database has become corrupt. This can occasionally happen (although not very often) as over time hundreds of tables are constantly added/removed by new plugins and themes. If you try to login to your WordPress site’s dashboard and are receiving the following error, it means your database is corrupt: “One or more database tables are unavailable. The database may need to be repaired.” It is important to note that you might only see this error on the back-end. Whereas you see the error establishing a database connection message on the frontend.

WordPress actually has a database repair mode which you can initiate. Simply add the following to the bottom of your wp-config.php file.

Then browse to the following location on your WordPress site: https://yourdomain.com/wp-admin/maint/repair.php. You will then have the option to repair the database. Or repair and optimize the database. Since you are probably troubleshooting an outage on your site at the moment, we recommend going with the repair database option as it is quicker.
