Hey guys I'm trying to make this work ... I'm installing Alicebot Scripts to my Invision Power Board Forum. They never rescripted it to work with the newer versions so I've been doing it slowly. But I'm lost for some reason to this ..

Error

Fatal error: Call to a member function query() on a non-object in /home/jordanr/public_html/forums/sources/lib/botloader.php on line 95

Appreciate any responses thanks!

I don't see where $DB is being initiated. PHP is expecting an object and is getting null

Hey do you have an MSN etc I could talk to you so I can try to resolve this problem?

Also botloader is ran from this prompt ... in a IPB Forum File

//---------------------------------------
// Start AIBot By MunjMedia Inc
//---------------------------------------
require( ROOT_PATH . 'sources/lib/botloader.php' );
$botloader = new botloader;

$botloader->ipsclass =& $this->ipsclass;
$botloader->forum = &$this->forum;
$botloader->parser = &$this->parser;

$botloader->startalice($tid);

This part appears to run fine is the $DB a part of the IPB forums? Possibly, or ???

I can try ??? $db = new database

This is in the DB_Prefs which might be part of it ...

define("LOOPINGERRORMSG", "Oops. I wasn't paying attention. Tell me again what is going on.");
define("LOOPINGLIMIT",150); // -1 for no limit
define("RANDOMCHANCECLEAN",100); // -1 to never check
define("MINUTESTOKEEPDATA",120); // -1 to keep forever
define("MINUTESTOKEEPCHATLOG",-1); // -1 to keep forever
define("DEFAULTPREDICATEVALUE", "Undefined");
define("PROGRAMEVERSION","v0.08");
// This is where all the AIML and startup.xml resides
$rootdir="../../aiml/";
$DB_HOST="localhost";
$DB_UNAME="********";
$DB_PWORD="*******";
$DB_DB="*******";
$errors="";

sql tables have been made in phpMyAdmin for the bot obviously. While the DB_Pref points the bot to this script, the $DB in the other script I beleive is trying to access the current ipb database? I dont know if that answers your question. The original script came as ipf_forums however I edited it to los_forums because my table prefix was "los_" ..

Let me know if you got any ideas!

There still is no $db instantiated...
The $botloader works, as it's been instantiated

PHP Code:

//---------------------------------------
// Start AIBot By MunjMedia Inc
//---------------------------------------
require( ROOT_PATH . 'sources/lib/botloader.php' );
$botloader = new botloader; 


I don't see the script requiring the database class, nor instantiating it using the same method as quote above anywhere...
