A couple of night ago, I ran into an issue that results in all my blog pages redirecting to the "install.php" page.
I was moderating a comment in the dashboard, approved it, tried to "view site" and now all I get is the installation page. I can't view any previous posts, I can't log into my WP account, I can't seem to do anything.
FYI, I'm running WP 2.6.
It seems like someone else ran into this problem w/ a previous version; the difference is that I always get the "install.php" page.

Any and all help would be greatly appreciated.
