I'm new to WordPress. A friend asked me to redesign his WP blog and I've installed it on my Mac using MAMP. I went through the database setup and imported the site's existing DB and added the tables. It all looks good, as far as I can tell, on the phpMyAdmin site.
When I go to url "localhost" in Chrome (and other browsers) I see the blog's front page, which is definitely local, but if I try to login, I'm sent back online. This also happens if I click on any of the links in the blog.
I've check that wp-config.php DB_NAME matches the name of the DB I downloaded. Anyone got any ideas what's going on?
