I wish I would have checked the forums before I tried doing this. I completely removed my WP installation from my server. All of the files were deleted, except for the "advanced cache.php". For that I get an error that says "couldn't find advanced_cache.php".
Most of the solutions I've seen on these forums are only applicable if the blog is still active. I do have a backup, so I suppose I could simply upload the backup and try one of those solutions.
But I'm hoping there's an easier way!
