My last upgrade was in Jan, and there was an error already then, which I managed to fix it - was a Tag Warrior issue.
That is *very* confusing, since your "old" blog clearly identifies itself as:
<meta name="generator" content="WordPress 2.0.1" />
...which, as I said in my other post, was released in January ... of 2006!

I'm very sure I just used the one-click install, so the db was definitely not touched.
Even using the one-click installs, the database should have been "touched" several times since 2.01 - the one-click installer is now installing version 2.3.3, and there *have* been database changes since 2.0.x.
Part of the "upgrade" process is usually a WordPress routine to update your database that you are askied to run after the upgrade. DId you do this after the "January" upgrade, and after this last upgrade?

Question, how can I delete everything from the parent directory, when even the old folder is a child under there too?
There are a couple of ways to go:
1) Use the shell to create some other directory in my user directory (the same directory that berried.net is in) and "move" (mv) the berried.net/old directory there, for safe keeping, and *then* delete berried.net's contents
2) Even better, just rename berried.net to something else (borked_berried.net?) and create a *new* (now empty) berried.net directory
Either way, once that is done you can just copy the contents of the "berried.net/old" directory (whatever it is now called
) back into the "new" berried.net directory.
