You need to copy the database settings from settings.php into a text file,
go into /settings.php and delete the database settings, line 203, next 
15 lines.
do an install by copy and pasting the user name and password into the 
"new install" from the text file.
Go through the install process and it will find the database and the 
site should run as normal
Also check that your files have the correct ownerships.
