big problem: wp-admin part unreachable after automatic upgrade

Hi, I’m Doris from The Netherlands.

I ran the automatic upgrade plugin, which is great, but… yesterday, two sites I updated lost their icons in the editor after updating, luckily we could restore this by re-installing the wpincludes directory.

The next thing that really worries me because I can’t solve it: on another site I also wanted to do the automatic update, but I was asked for ftp information.

After I provided this, I have a huge problem: I can no longer reach the wp-admin part, it gives the message: Nothing found for Wp-admin Page Php

I really hope someone can help me out! I’m totally clueless off what to do now?
