Permalink issue with IIRF

[Sandra]

Hello -

I just started working on a new site using Black Canvas ver 3.0 at http://cameronmaclennan.com

My site is hosted on a Windows server and I have set up IIRF to allow pretty permalinks.

My IsapiRewrite4.ini file is as follows:

RewriteRule ^/(?!index\.php|iirf|wp-|xmlrpc)(.*)$ /index.php/$1 [I,L]

However, when I set my permalinks to custom structure

/%postname%/

my test post does not show on the home page and I am getting "The page cannot be found" error when I try to access pages, posts and archives on a new site

Everything loads fine when I use any the default permalink settings.

I have not had this issue with any of my other sites that do not use a StudioPress theme. Any ideas greatly appreciated.

Many thanks
sandra
