I'm a WordPress newbie and have been working on a website for the past few weeks. I'm currently using localhost as the host server. Just today, after signing on and getting to the Dashboard, I find I can't connect to the Weblog Tools Collection sites - I get a "Error establishing a database connection" message. Other links work fine from the Dashboard. The website I'm working on also works correctly and I'm able to edit it from within the WP admin. I know this worked before today because I've downloaded some of the themes. Any ideas? Thanks in advance.
