We have to install a new wordpress for every new site. Else we can update the wp-config.php file with the latest database and username info. This is what I get through the form.
Please do rectify if the above context is wrong.
Well the problem is I have tried every possibilities by installing a new wordpress and by changing the the database, user name etc. etc. in the wp-config.php file, nothing is working and I cannot install the new wordpress. In both the cases it shows the same error
'Error establishing a database connection'
host is localhost
