Fatal error: Call to undefined function virtual()

Hi all ..
2nd post and having problems already
IIS7.5 , win2k8r2 server VPS
i've installed a test setup on my server to see how things work
and after install the index page gives a
Fatal error: Call to undefined function virtual() error on line 40 .. that line being
<?php virtual("/CSSMenuWriter/cssmw_home/menu.php"); ?>

i recall having php virtual errors on other windows server in the past do manually changed the line to read <?php include("CSSMenuWriter/cssmw_home/menu.php"); ?> which now works.
there are however (i assume) many instances of this kind of 'call' within the setup as i get the error on other pages i have not yet looked at
is there a global workround for this ? is it a know issue ? and what should i do , hopefully the answer is not edit all pages by hand :D

Fixed : Go to Site -> Manage Sites. in the site manager, select your site and click the edit button. On the local info tab, change the "Create Links Relative to:" option to "Document"

Yes, setting the "Create Links Relative to:" option to Site will cause Dreamweaver to use the virtual() function which is only supported on some Apache servers.

changing that to Document will cause Dreamweaver to use the require_once() function which is more widely supported.

I just encountered this issue. I was able to resolve it via the following sequence of steps, though I am not sure if they are all required or not! In my case, the "Links relative to:" option was already set to "Document".

This worked on an XP SP3 box running CS4.

1. Reset DW's window workspace, Window-Workspace Layout-Reset. Closed DW.
2. Deleted the cache file (\Documents and Settings\user name\Application Data\Abobe\DreamweaverCS4\en_US\Configuration\WinFileCachexxxx.dat
3. Opened DW's Site Manager - moved "Links relative to:" from "Document" to "Site Root".
4. Closed DW.
5. Opened DW's Site Manager again - moved "Links relative to: from "Site Root" back to "Document".

Poof - magic! Hope this helps.
