how about change
to

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1 [L]
</IfModule>

Thanks that worked. Why doesn't it work with the '/' but with the '?' ?

I have a large number of virtualhosts to convert and am worried about little rewrite issues like this.

good news. have you tried on apache? if not working under apache, then the rewriterule not written properly.

yes the rewrite rule worked on apache.

why did the ? work and not the /, i imaging it's a fairly common rewrite?
