Alternatively, you can patch your web server to define DOCUMENT_ROOT correctly.


I'm getting this error:

=======================================
Unexpected critical failure
Critical Error: Document Root not set, Edit local_links_init.php
=======================================

I'm assuming this is the error you mentioned?

How/where do I "define the constant LDM_DOCUMENT_ROOT"

or How do I patch the server?

thanks..

The file local_links_init.php is contained in the includes/ subdirectory of the release zipfile and uploaded into the forums/includes/ subdirectory.

Open the file using a text editor and find these lines:

if ($_SERVER["DOCUMENT_ROOT"]) {
	define('LDM_DOCUMENT_ROOT', $_SERVER["DOCUMENT_ROOT"]);
}
else {
// If you are running the IIS web server in CGI mode on Windows or if otherwise warned, uncomment and edit this line
//	define('LDM_DOCUMENT_ROOT', '/path/to/your/site');
}

You need to replace the line

//	define('LDM_DOCUMENT_ROOT', '/path/to/your/site');

by the correct directory path to your web site, e.g.:

	define('LDM_DOCUMENT_ROOT', '/data/www-root/mysite');

You can generally figure out what is your '/data/www-root/mysite' by going to your vbulletin/admincp/maintenance/php info page, and taking a look at the listing. I can't easily tell you what line to look for, as I do not have a windows-based IIS server available.

If you have problems with this, send me a PM with site details and a username/password for an account with admin privs on your board, and I'll take a look myself.
