Ok, thanks for your response - Still a little confused why the forum is still live and letting people register and try to ask questions if they will never be answered!
My issue here is that I after failing to install 2.0.5 with the ecommorce bundle, I went for 2.0.4 - the plain CMS version. This installed perfectly well, but is missing the /go directory. I've looked at some other posts that mention this and that it's a 'route' instead of being a physical directory?
I've made sure that mod_rewrite is loaded, but not sure about allowoverrides. In httpd.conf I've temporarily set this to:
Require all denied
Not sure what the syntax is at the moment - will check that shortly.
