The version of WP my blog was running was 2.2. I followed the instructions like I've done so many times to make backups and copy the new files over. However, this time, when I go to the upgrade.php file, I get a blank page -- no action whatsoever.
I've looked here for similar posts, but some were either not resolved or the solution did not work for me. I'm using Firefox as I always have during this process.
Now that my blog is down, I'm eager to getting it going again.
