userinfo array is empty?

[webForum-dev]

Hello, I'm trying to write a plugin using the showthread_start-hook.

I want to get the current logged in user userid.

I have tried alot of things.
$vbulletin->userinfo['userid'];
$vbulletin->userinfo[userid];
$bbuserinfo[userid];

But they are always empty, evfen if I'm logged in.

I also tried showthread_complete but userinfo is still emtpy.
I also tried to print the whole useinfo-array but that is also empty.

Any ideas?
