Installing Drupal

When go to the install.php page on my site, I receive this error:

Fatal error: Call to undefined function module_list() in /home/mcwh/public_html/battlefieldbb.com/includes/install.core.inc on line 260

Any suggestions? Thanks.

I am unable to install the CiviCRM Starter Kit Distribution because I can't get past the "verify requirements" step.

Error 1
"Warning: array_merge() [function.array-merge]: Argument #2 is not an array in drupal_check_profile() (line 1165 of /home/xxxxxx/public_html/includes/install.inc)."

Line 1165: $requirements = array_merge($requirements, $function('install'));

How should this line be edited to correct the error?

Hello, Thanks for the sample on http://drupal.org/node/1043724 , now I can share user data between http://v9zz.com and http://bbs.v9zz.com , but I want to share user database across hosts, how can I do?

I can't share user images between if although I used same database between my bbs and main site, anyone has done that ok?

I don't know whether it's appropriate to question here, can anyone help me? Thanks.

I've created a duplicate of a fully functioning Drupal site by simply duplicating the database, copying all the files into another directory then changing the database connection in settings.php. I then created a subdomain which points at this directory.

The front-end of the duplicated site works absolutely fine but for some reason when I try to login using any account I get "Access Denied". The user accounts in the duplicated database are all identical to those in the master database so I can't see any reason why this isn't working.

I first tried my luck in #drupal then seeing no reaction tried #drupal-support which also had the same reception. The IRC post was

Is there a way to make a multisite ip-based site? I've made 2 vhost for 2 local IPs pointing to the same drupal root which contained in /sites directories of the same characters as the IPs with the same settings.php $db_url but different $db_prefix and $cookie_domain as http://drupal.org/node/201673 however when installing, drupal uses the default setting.php (first I suspected so because it had a different $db_prefix 'default' but then I used a different $db_url so I'm pretty sure). so I really don't know what else I can do to make an IP-based multisite. I was hoping not to have to setup a local dns. :| thanks for you help :)

which link is entitled Sharing users and content across multiple sites. That was the core of my issue.

A little more information: The httpd.conf found on my homepage includes

<VirtualHost 127.0.0.1>
# using default: 'Main' server configuration
</VirtualHost>
