Incorrect login credentials, corrupted word press file, a corrupted database or too much traffic.

To solve the database error in word press we have the following ways:-

1.) Contact your Web Host Provider

If you are frequently facing trouble with your website, then it is highly probable that your web host is at fault.
Nowadays, web host providers respond to their clients via live chat.

Start by communicating them on live chat. If you are experiencing a database error, ask them the following questions:-

Does the database server has some problems, and
Is there any disbelieving activity going on the server.

2.)Ensure your plug-ins and themes are not corrupted

Plugins and themes might get corrupted after updating, adding external services or due to faulty written codes.

To get out of this problem, you have these solutions:-

Connect to your host via FTP with the tool Filezilla.To get connected insert your login credentials i.e. user name and password, if you don’t remember these credentials then get them through the early e-mails you got from your host. The other way is, get the credentials from the live chat with the host providers.After getting the credentials, connect to the server and navigate to the WordPress root folder which could be named either “www” or “public_html”. Ensure that you are in the WordPress root folder if it contains subfolders named “wp-content”, “wp-includes” or “wp-admin”.
Get into the “wp-content” folder and change the name of the “plug-ins” folder to some other name of your choice.
Visit your site again and check if the error still persists.
After renaming, if the error continues then convert the folder name back to plug-ins.
Still, if the error occurs, open up the plug-in folder and individually alter the name of each and every plug-in. The best way to do this is by adding an underscore after the name of the plug-in.
Again, if the error keeps on triggering then perform the same procedure with the theme folder.

This will eventually lead to fix the problem with the corrupted plug-in or theme. It is one of the best ways to solve the WordPress database error.

3.) Ensure your database is not corrupted

The WordPress database error can also occur when the database gets corrupted.

First, check the WordPress dashboard SiteName.com/wp-admin if there occurs “error establishing a database connection”, then your database is not at fault
Apart from this, if it shows some other error message, like “can’t select database”, or “one or more database table are available” then give a deep think on this error message.
After receiving such kind of error messages, it actually means that your database needs to be repaired.
To do this, get connected to your site via Filezilla. Go to the WordPress root and download the file “wp-config.php” on your desktop.
Now add a line at the end of the file. [su_note note_color=”#e6e6dd” text_color=”#e90909″]define(‘WP_ALLOW_REPAIR’, true);[/su_note]
Now upload the newer version of the file to your site(via FTP).
Visit site sitename.com/wp-admin/maint/repair.php.
WordPress will open up a new window with two buttons i.e. Repair Database and Repair and Optimize database.
Click on any button, once the repairing process finishes, go back to your site if the error persists.
If the error still persists, then upload the file by removing the new line you appended in the file and check your site for error.
This would eventually lead in solving the database error, If the error still occurs then go for the next solution.

4.) Check the surety of database connection credentials.

WordPress access credentials like user name and password are fixed and generally do not change their own. If the user forgets this, then one must get them by contacting the hosting provider via Filezilla.

But it is observed many- a- times that making changes to the files of the site, or the hosting environment can result in the change of access credentials. The user keeps on trying with the older credentials he has, and in turn, he receives a database error message.

The error can be fixed by taking the four lines from the wp-config file and sending these lines to your host via live chat. The hosting provider representative will check if these lines are correct or not.

define(‘DB_NAME’, ‘user_db’);

define(‘DB_USER’, ‘user_username’);

define(‘DB_PASSWORD’, ‘user_pass’);

define(‘DB_HOST’, ‘localhost’);

If these credentials, would be found wrong, then the representative will give you correct details which you can use in your “wp-config.php” file.

After, this uploads the new file via FTP. This will remove the WordPress database error.

5.) Get the default WordPress files back

Files may get corrupted by consistent hacking attempts, corrupted themes or plug-ins, etc. The only solution to solve this issue is by downloading the pure version of WordPress.

Download the latest package of WordPress from here.
Unpack, and browse the unpacked archive.
Delete the “wp-content” folder.
Get connected to your website through FTP.
Go to the WordPress root.
Upload the newly downloaded files.
Get back and see if the error still exists.

Above is the eventual solution for the WordPress database errors. After trying all these solutions, if the error still persists then go to your web host support service provider and ask them to solve the issue.
