403 forbidden error after logging in

Hi all,

Just installed a new WordPress installation and all seemed to go well. I’m able to get to my wp-login.php and log myself in just fine. But after that, I can’t get to my dashboard at /wp-admin/ because it throws a 403 forbidden error. I also get a 403 when I try to access the blog directly at its URL. I tried changing the permissions on the directory to a few different configurations, but nothing worked. Any tips?
