user & password in wp-config not working?

I have edited the wp-config.php file with the proper dbase, user, pswrd, etc – but cannot login to wordpress… When I look at another one of the co’s websites wp-config and try using the user & pword from that file, it doesn’t work either. What am I doing wrong? the sites are hosted on Bravenet and installin WP on one has made all but the landing page inaccessible! mcsquaredconsulting.com
