Then you’ll need to access your file, to be more specific, you need to get to wp-config.php

Then find something like:
define('DB_NAME', 'your_db_name')
And so on.

Take a look at those define and match the variables with the credential you found at vPanel > MySQL Databases. After that, save and refresh your browser (cache may also need to be deleted).

Please where will I see the wp-config.php ? Is it inside my infinityfree cpanel or where? You know I can’t login to my wordpress dashboard( http://nairaville.cf/wp-admin and
http://duchng.cf/wp-admin ) at this time. Also, to be more specific the vPanel > MySQL Databases can be found in my Infinityfree cpanel, right?
