VB 4.2.2 - moved to new server - dateformat wrong

[VCCN]

Hi guys,

I've just moved our forum to a new server.
Everything works fine expect from the dateformat in the forum (it's wrong)

Even if i change this in forum-options, the change is not reflected on the forum.
Any ideas where the problem might be?
system-locale on server is set to Norwegian, did not help.

What i have:
MM/DD/YY (Us format)

What i want:
DD/MM/YY (EU format)

I have tried all different options according to PHP, but no matter what i type in the options page, it doesn't affect the forum.

I appreciate all help i can get, as i have two hours before i need to put the forum back online.
