After re-reading what i wrote above i dont think i was too clear on what the problem is.

My current site is a 1.3.5 that is live is mysite.co.uk/shop and doesnt have this mod installed on it, over the past few weeks i have been building a 1.3.8a test site in mysite.co.uk/test i have just installed your mod and put my site live within the root so its simply at mysite.co.uk it will take a while for this to become within search engines as its literally just a few hours old of being live, but my main problem is that when i try to go to mysite.co.uk/shop it doesnt load and throws a 404 error as with mysite.co.uk/blog, i have scanned through this whole thread and i couldnt find another post by someone that has multiple databases within the one domain, im pretty sure i just need a rewite code but im stuck at locating what the code is i need.

I hope you can help me out, as im really stuck as i cant get into my /shop/admin page to access the sales.

Cheers
Ben
