Sidebox Anywhere is not working for me

Hello all,
I am using ZC version 1.3.9c on WAMP Server (for development). I tried to embed Specials sidebar, using Sidebox Anywhere version v1.3.8, to my a CMS site but without luck.
On the CMS, I have this code as per instruction:
$zcSBmodule = 'whats_new.php';
require ("I:/wamp/www/onlinestore/single_sidebox.php");
However, my attempt is without luck.
I managed to trace it to these lines inside includes/autoload_func.php

  if (file_exists(DIR_WS_INCLUDES . 'init_includes/overrides/' . $entry['loadFile'])) {
    $baseDir = DIR_WS_INCLUDES . 'init_includes/overrides/';
  }

When it reached file_exist, the whole script just crashed without any output.
It looks like got to do with $entry['loadFile'] but I am not experience with ZC to know what is going on.
Any help would be good.
Note though, the ZC site works.

Regards,

Robert Bui

Hmmmm I've eventually traced the issue to this line inside init_db_config_read.php

$configuration = $db->Execute('select configuration_key as cfgkey, configuration_value as cfgvalue
from ' . TABLE_CONFIGURATION, '', $use_cache, 150);

I also made a test script in which case I placed in the same directory as ZC. It works as expected.

So, my suspion would be got to do with file/directory path in one of the variables.

I called the single_sidebox from the root of the site while ZC lives under a directory underneath the root. This is not working....

OK.... I worked out it's conflicting with Joomla. Still trying to work out WHAT and HOW to resolve.
