I've got two scripts:

hack_install.php

error_reporting(E_ALL & ~E_NOTICE);

$path_to_install = str_replace("hack_install.php", "", $_SERVER['PATH_TRANSLATED']);
$install_dir = opendir($path_to_install);
while (($file = readdir($install_dir)) !== false) {
if (strpos($file, "hack_install_b") !== false) {
$versions[] = $file;
}
}
unset($install_dir);
unset ($file);
asort($versions);
foreach ($versions as $version) {
$theversion = $version;
}
unset($version);
unset($versions);
require_once($theversion);

and hack_install_b1.php

define('THIS_SCRIPT', 'hack_install');
define('INSTALLER_BUILD_NUMBER', '1');
define('INSTALLER_VERSION', '1.0');

require_once('../includes/config.php');
chdir("../$admincpdir");
require_once('./global.php');
require_once('./includes/adminfunctions_template.php');
require_once('./includes/adminfunctions_language.php');
require_once('./includes/hackfunctions_b1.php');
chdir('./install');

I get the above error with both...

What error?

Remove this in hack_install_b1.php and see if it works.

Not sure why that line is there.

it tells me

Fatal error: Call to undefined function: print_cp_header() in /var/www/site/forums/install/hack_install_b1.php on line 33

which is

print_cp_header('Hack Installer', '', "<style type=\"text/css\">

I also do not have such required file in my includes:

require_once('./includes/hackfunctions_b1.php');

just installed and the shoutbox doesnt show on forumhome :( anyone got the code so i can add it to forumhome template :)

I got it by doing like you said about config.php and by hardcoding the ../$admindir into ../admincp

Everything installed fine, except for templates of shoutbox.php all messed up and a javascript error at line 115, and another one when I click on the quicklinks in navar. Problem is line 115 is just the css. I got a feeling it is coming from the WYSIWYG editor.

Also, can the "shoutbox closed" error message template be changed? It is bringing up the whole header and footer in the forumhome iframe box.

That's what I get for suggesting a fix at 1 AM.

That's because it is checked at the top of the file.

I'm going to have to check it on forumhome as well, though I thought it was checked there.
