all u need to do is :
open wp-config-sample.php
step1:define(‘DB_NAME’, ‘putyourdbnamehere’);——very importent
step2:define(‘DB_USER’, ‘usernamehere’);
step3:define(‘DB_PASSWORD’, ‘yourpasswordhere’);
then change the name “wp-config-sample.php”into “wp-config.php”
the themes lack of style.css course maybe it 2.7
