webinstall failed, help required urgently.

Should have done this tomorrow as I have to go out shortly, webinstall failed and has left me with no site and the following error.

Unknown column 'a.attachment_type' in 'field list'

[Illori]

please run upgrade.php

[clothahump]

upgrade.php has just crashed the server.

[Illori]

crashed it in what way?

[clothahump]

Completely crashed, server offline completely

[Norv]

How did it crash, what exactly happens when you run it? Say you write upgrade.php in your browser, and hit Enter. What happens?

[clothahump]

Crashed while backing up database sessions table, restarted and ran through without backing up and all looks fine now, panic over.

[Norv]

I hope you did take a backup anyway?
You should ALWAYS take a backup before upgrading. Using phpmyadmin would be best.

[clothahump]

Back up done at midnight so would not have been much lost.
