query_first_slave() error when trying to use vBulletin API outside of vBulletin

[nvitremi]

Hi,

Since the past two days, the only thing I'm trying to do with vBulletin is to display a login form or a user information box (when the user is logged in) on every pages of the site, including those not in vBulletin. That's it -- nothing fancy. I do not need or want full integration capabilities -- just display a user information box or a login box whether the user is logged in or not.

I followed a tutorial I found on this site and tried to make a page outside of vBulletin's directory and still use vBulletin's API. Even though I followed the instructions to the letter, I can't make a page outside vBulletin. I get the following error message:

Call to a member function query_first_slave() on a non-object in /var/nvisionit/projects/precisionnutrition/www-newcms/forum/includes/functions.php on line 1303

Is there anything I can do to make this thing work once and for all?

Any help will be appreciated. Thanks in advance!
