Can’t access backup database

Hello, I upgraded from 1.5.1 to 1.5.1.3, but I messed up.

On the one hand, I deleted my wp-config.php file.

I made it again, just as it was before… but then when I tried upgrading, it gave me three errors, then told me there is only one step, and that I was ok.

But when I tried to log in, it said that it doesn’t seem like I have installed yet. So, I guess I shouldn’t have, but I re-installed.

Thankfully I had backed up my database. I checked, and it hadn’t been tampered with. I put the backup back up there on the server.

But how can I tell it to look at the database again? I mean, I look at phpMyAdmin, my old DB is there, but all I get in the blog (blog.spitaki.org) is a Hello World…

Any idea what I’m supposed to do?

Thanks a lot,
Kostis
