404 after installation

[webbly]

Hi all, I really hope someone can advise on this error as I'm really keen to use Arfoo!!

OK so the installation goes ok, I get a green pass on everything, installation completes, but when it asks to click on the login to admin, it redirects to:

http://clairewallacehairdressing.co.uk/ ... main/logIn

I get a 404 error on this page as the directory does not exist. Ive tried installing with and without the mod rewrite as I assumed it might be a .htaccess problem, and maybe still is??

Has anyone else had this?? Is there a solution or am I being a complete tit and doing something wrong?
