/showthread.php was not found on this server

Hi
I've done a fresh install of v3.7.0 b6 and am starting it up as a new forum so the database is new. There are no mods, all I've done is changed the colours.

(I previously had a working version of 3.6.8 PL2 on the same server.)

The problem I am having is that you cannot view the threads that have been posted by the new members today. They have never been viewable.

I get this browser message when trying to access a thread

Not Found

The requested URL /showthread.php was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.2.6 (Unix) mod_ssl/2.2.6 OpenSSL/0.9.7a mod_bwlimited/1.4 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 Server at www.thewinebar.eu Port 80

forum is at: http://www.thewinebar.eu

Many thanks for any help

PS - the file showthread.php IS on the server within the forums folder. I can't even access it by typing it in as a standalone url, but all the other php pages work, thus I don't think it is a vbulletin problem but have no idea.

This is the contents of the .htacess file:

RewriteEngine on
RewriteCond %{ENV:rwdone} !^yes$
RewriteCond %{HTTP_HOST} !www\.thewinebar\.eu
RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9\-]+)\.thewinebar\.eu
RewriteRule (.*) /%2/$1 [E=rwdone:yes,L]

Double dutch to me.

You got me on that one. I have no idea what it means.
