It is a very common problem of establishing a database connection while migrating your hosting to another hosting provider.
Why does this problem happen?
- If you have forgotten to upload wp-config.php file in public_html folder.
- If you have made a new WordPress installation in another server and forgot to change the database name, database username, database password in the wp-config.php file.
This error is all about the error in the wp-config.php file because this is the file that helps to connect WordPress with the database.
How to solve this error?
Method 1 – Copy the existing wp-config.php file and paste it in the new hosting provider public_html folder.
Method 2 – You can also copy the database name, database username, and database password details and put it into new wp-config.php.
- Database username
- Database password
- Database name
These 3 things are only necessary to put into the wp-config.php file to establish a database connection.
I hope you can solve your problem easily with the method. If any questions please ask, or if you solve your problem, please comment on me.
