Help! Strange error…

Hi all… Does anyone know why I’m getting the following error? This is the second time I’ve installed on this domain. The first time it worked well but I was tinkering to make it compatible with another problem and screwed it up so I had to reinstall.

I reinstalled the database on the server. One thing that may be important is that I can’t get a file to disappear in my Local Files from the original install (blog>wp-content>themes) and when I uninstalled, Dreamweaver told me I was (I think) basically orphaning some links.

OK that’s all background, here’s the meat:

Warning: require_once() [function.require-once]: Unable to access ../wordpress/wp-config.php in /var/www/vhosts/lastcity.org/httpdocs/wp-admin/install.php on line 9
