[Koha] internal error

I have finally reached the point where I am trying to load up the = hompage for Koha. I followed the instructions for installing Koha on = Debian (sarge). After going to http://myip:8080 it looks like my Koha = is going to load then I get an Internal Server Error. When checking the = apache2/error.log I read: access denied for user 'www-data'@'localhost' (using password: NO) at = /user/local/koha/intranet/modules/c4/context.pm line 411 Any help would be greatly appreciated. Thanks, Derek
