Database connection error (2): Could not connect to MySQL.

[keyboard-man]

Hi all,

I sold my website yesterday, the new owner changed the phpmyadmin password and the configuration.php password but once he did he got this error Database connection error (2): Could not connect to MySQL.
and when he put the old password back it works, anyone know why this happen ? any idea or advice please ?
thank you in advance

Because the database password is stored in the file configuration.php. The variable is $password

The user can change the password in the Global Configuration and then change it in the database.

Thank you for your answer, but this is what he already did, he changed the password in configuration.php various time in both Global Configuration and in the database but it doesnt work , but when he come back to the old password it works

Whether the user changes the database username as well? If the answer is Yes then the user has to GRANT ALL PRIVILEGES to the new username.

no he did not changed database username, because in this hosting you only create new database username, you cant change new one , he only tried to change password, it's strange because with the older password it work, but whi a new one it doesnt
