Yesterday I was enough idiot to "CHMOD -R 777 /"
Yes. I CHMODed the root.

Then I lost access to FTP, SCP and SSH, with only the web interface working fine.
Today I reinstalled the B3 OS from an USB stick.
After the reinstallation, the above problems are the same, but now I can't open the admin panel.
My website's users will kill me.
Please help me, as I will leave Bucharest in less than three days.
