Copy live website to localhost

I have a question about copying a live website back to my localhost. I've tried many options, and It only results in it displaying the main page with the content that is of the same as live. The problems happen when I try log in to the admin, or click on a content type webpage -> this directs me back to the localhost page.

I've copied all the folders back into a fresh localhost folder, exported the live DB and imported it back with phpmyadmin, but I only ever get the problem listed above. I've changed all the necessary settings in the settings.php page, but no luck

Any ideaS?

Thanks
