Cant connect to DB

[Proweb]

During the start up of the site, it is
giving me the database server is not found error although the database server
is localhost. You may need to contact the prestashop support and inquire as to
why this is happening. I have attempted to connect via the software without
luck. I can connect to the database via the server with the username and
password.

You have added a new user. SQL query: GRANT USAGE ON * . * TO
'prestashop'@'localhost' IDENTIFIED BY '*********************' WITH
MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 ;

CREATE DATABASE IF NOT EXISTS `prestashop` ;

GRANT ALL PRIVILEGES ON `prestashop` . * TO 'prestashop'@'localhost';

Database server was not found. Please verify the login, password, and database
server name fields.

You can verify this via the http://bucksnbass.com/install link here.

Check mysql-server is up

Try removing the database and user, then creating again. Be sure to grant all privileges to the user.
