Strange Include Problem

[Fubs]

I am trying to put a website live, works fine on my laptop, but when I upload it to my hosting provider, I am getting a strange error.

I include a lot of files, and all of them have been succesfully included except for one.

The error message that I am receiving is:

Warning: Failed opening '/templates/html_menu.php' for inclusion (include_path='') in /www.myurl.com/templates/html_header.php on line 32
include(/templates/html_menu.php)

The code I am using to include is this:
<td>
<?include ($vtemplatedir.'/html_menu.php');?>
</td>

Every other include I have seems to be working - its just this one. The only differance I can see is that this is being called from another html file. My structure looks like this:

index.php
-includes
/templates/html_header.php
-includes
/templates/html_menu.php

I have other config files that include each other in a similar way and they are working.

If anyone can shed some light on this it would be appreciated.

it seems to be because you are including the wrong path. include() reads from the root directory, not the web root. so if $vtemplatedir = "/templates" on unix, that becomes /templates and on windows, C:\templates
try changing $vincludedir to "./templates" or just directly do
include("./templates/html_menu.php");
