You proberbly need to edit config-int.php manually, open it up and change the following to something like this

$vbpath = "/home/*****/public_html/forum/foros/";
$vb_urlpath = "http://www.jeeperos.com/foros/";


global.php is in /foros/ it is a vBulletin file and doesn't need to be edited, you most likely have one of the above set wrong hence it can't find global.php

"And for the record, I hit the "PhotoPost Internal User Registration" and add admin, pass and such, then go to the admin login, put the usr/pswd and sends me to the same white page"

Did you change

define(VB3_INTEGRATION, 'on');
define(VB3_ENHANCEDINT, 'on');
define(VB3_COMMWYSIWYG, 'on');

to off in config-int.php
