Let’s take a gaze at how to go about troubleshooting this difficulty.

Does the difficulty happen for /wp-admin/ as well?
First thing you should do is to make sure that you are getting the identical mistake on both the front-end of the site, and the back-end of the site (wp-admin). If the mistake note is the same on both pages “Error setting up a database connection”, then proceed up on the next step. If you are getting a distinct error on the wp-admin for example certain thing like “One or more database tables are unavailable. The database may need to be repaired”, then you need to repair your database.
You can do this by adding the following line in your wp-config.php file:
define('WP_ALLOW_REPAIR', true);
 Once you have done that, you can see the settings by visiting this page: http://www.yoursite.com/wp-admin/maint/repair.php

Remember, the user does not need to be logged in to get access to this functionality when this define is set. This is because its main intent is to repair a corrupted database, Users can often not login when the database is corrupt.

Ascertaining the WP-Config file
WP-Config.php is likely the lone most significant document in your entire WordPress setting up. This is where you identify the minutia for WordPress to connect your database. If you altered your root password, or the database user password, then you will need to change this document as well. First thing you should always ascertain is if everything in your wp-config.php document is the same.

1	define('DB_NAME', 'database-name');
2	define('DB_USER', 'database-username');

3	define('DB_PASSWORD', 'database-password');
4	define('DB_HOST', 'localhost');

Recall your DB_Host value might not habitually be localhost. Depending on the host, it will be distinct. For well liked hosts like HostGator, BlueHost, Site5, it is localhost. You can find other owner standards here.

Some folks proposed that they fixed their difficulty by restoring localhost with the IP. It is common to glimpse this sort of topic when running WordPress on a localizedized server natural environment. For demonstration on MAMP, the DB_Host value when altered to the IP may appear to work.

1	define('DB_HOST', '127.0.0.1:8889');

IP’s will vary for online web hosting services.
If everything in this document is correct (make certain you ascertain for typos), then it is equitable to state that there is certain thing incorrect on the server end.

Ascertain your world wide web owner (MySQL Server)

Often you will notice this mistake establishing database attachment when your location gets swarmed with a lot of traffic. Fundamentally, your host server just will not handle the burden (especially when you are on distributed hosting). Your site will get actually slow and for some users even output the mistake. So the best thing you should do is get on the telephone or live chat with your hosting provider and inquire them if your MySQL server is responsive.

For those users who desire to check if MySQL server is running yourself, you can do a few things. check other sites on the same server to glimpse if they are having the issue. If they are furthermore getting the same error, then most decisively there is certain thing incorrect with your MySQL server. If you do not have any other site on this identical hosting account easily go to your cPanel and try to get access to phpMyAdmin and attach the database. If you can attach, then we need to verify if your database client has adequate consent. conceive a new file called testconnection.php and paste the following cipher in it:

1	<?php
2	$link = mysql_connect('localhost', 'root', 'password');

3	if (!$link) {
4	die('Could not connect: ' . mysql_error());

5	}
6	echo 'Connected successfully';

7	mysql_close($link);
8	?>

Make certain to restore the username and password. If the connected effectively, then it means that your client has sufficient consent, and there is certain thing additional that is wrong. Go back to your wp-config document to make sure that everything there is correct (re-scan for typos).

If you cannot attach to the database by going to phpMyAdmin, then you understand it is certain thing with your server. It does not inevitably means that your MySQL server is down. It could signify that your client does not have sufficient consent.

In our case, our MySQL server was running. All other sites on the servers were working fine except for WP Beginner. When we tried going to our phpMyAdmin, we completed up getting the error:

#1045 – Access denied for user ‘foo’@'%’ (using password: YES)
We got on the phone with HostGator and their support rapidly discovered the difficulty. someway our user’s permissions were reset. Not certain how that occurred, but apparently that was the cause. They went back in and restore the permissions and we were adept to get the location back live.

So if you get the get access to refuted mistake in either connecting to your phpMyAdmin or through testconnection.php results, then you should contact your owner right away to get them to fix it.

Solutions that Worked for Others
It is significant to note, that these may not work for you. Use at your own risk and make certain that you have adequate backups if anything proceeds incorrect.
Deepak Mittal said that his client was getting the mistake that database desires to be fixed. Even after repairing the database, the mistake did not go away. He tried various things and at the end, the topic was the location url. Apparently that was altered which initiated the error to persevere. He ran the SQL query by going to phpMyAdmin:

1	UPDATE wp_options SET option_value='YOUR_SITE_URL' WHERE option_name='siteurl'

Make certain to replace YOUR_SITE_URL with the genuine url example: http://www.yoursitename.com. The wp_options will be distinct if you have changed the default WordPress database prefix.

This seemed to fix the issue for him and couple of other ones that commented on his post as well.

Socinus proposed that he was able to connect the database with testconnection.php, so he altered the wp-config.php user to the root user. WordPress begun to work flawlessly fine. Then he reverted the settings back to the database-user, and it proceeded to work. He could not number out what was incorrect, but concluded that it was a typo.

Cutewonders suggested that they taken the content of active_plugins in wp_options table and revised the contents of recently_revised. fundamentally that seemed to fix the difficulty. Please their full answer here.

We read on many causes that users easily uploaded a new exact replicate of WordPress and it fixed the error.
