I would love to find some help before I have to trash the whole thing, start over and migrate content from Blogger (which has the advantage of working) or by cut & paste.
I followed the Codex instructions (twice so far) to upgrade from 2.1.3 to 2.2. The result was a blank screen and no access to /upgrade.php /install.php or anything else except the read me (from the web host's control panel).
When the second upload failed I followed the Codex and a tutorial with pictures to copy my backed up database to MySQL. The database exists, the backups work but it left me in exactly the same place -- no blog, blank screen at http://7colorlagoon.com/blog1.
Any advice before I give up and start over with Blogger files and cut & paste? Another wasted 10 hours or so. WP now threatens to do this dastardly deed every few months!
