This kind of blunder happens when WordPress can't make a connection with the database. Many reasons are there which can impact your WordPress database Connection, which is sometimes hard to debug.

Causes behind the problem:

This error developing a database Connection problem may be accomplished through off base database statistics in your WordPress settings, degenerate database, or an unaffected database server. In keeping with the manner, WordPress makes use of a database to save all of the articles and other web page data. It at that point interfaces with the database each time someone visits your web site.

WordPress needs the accompanying data for associating with the database:

• Database name
• Database username
• Database password
• Database serve

This data is put away in your WordPress design record called wp-config.php.

If any of these things are mixed up, WordPress will disregard to hook up with your database server, and you may see the error putting in a database affiliation goof.

Aside from wrong qualifications, this blunder can likewise show up if the database server is down, or the database documents are degenerate.

Conceivable arrangement:

• Check database connection: The most well-known purpose behind database Connection mistake in WordPress is mistaken database qualifications. If you have as of late moved your WordPress site to another host, at that point, this could be a doubtless reason. Your database certifications are put away in the wp-config.php record. It is the WordPress configuration file that includes essential information about the database.
• Check Database host: If the database connection is not your problem, then at that point, you might need to ensure that you are utilizing the correct database host data. Most WordPress hosting environments generally use localhost as a database host. Be that as it may, some oversaw WordPress hosting organizations utilize separate servers to host databases.
• Database Repair: If you are getting another mistake on the wp-administrator, for example, something like "at least one database tables are inaccessible. The database may be fixed", at that point, you have to fix your database.
• Database server status: Now, check once the state of the database server, WordPress still can't associate with the database; at that point, MySQL the server might be down.

This could occur because of substantial traffic on a server. Fundamentally, if you are using shared hosting, then a high chance to face this issue.
