This means that the includes/configure.php file couldn't be found, OR the path created by DIR_FS_CATALOG and your includes folder ... wasn't accessible.

When you edited the configure.php file contents on your PC and then uploaded it, had you marked the file as writable on the server first? If it's read-only, you won't be able to upload over it.
