I have a small business Yahoo account and I am having trouble seeing and administrating my blog.
From the manage blog area, when I click the link to view my blog, I get a ‘cannot find page error’. When I add www in the address bar, I can view the blog. When I try to get to the administration area for my blog I get a ‘cannot find page error’, I tried adding www to the address and it still does not work.
Your account is 1 hour old and linked to an empty blog here – BUT you mention a Yahoo account – so you probably have a WordPress.ORG install hosted by Yahoo which means our answers here might not help.
Your site is not hosted on WordPress.COM, this site is for support of sites hosted on WordPress.COM. You should address your questions to WordPress.ORG the keepers of the software you are using: http://wordpress.org/support/
