Three days ago (2.5 to be precise) I migrated my domain to a new server. The transfer of the domain has gone through, and I have access to my cpanel with the new host, so I know that for the last three days people have had access to my blog. But whenever I try to access it, either through the URL or through my WordPress admin page, I get "can't select database." My config file is correct, and the DNS has been properly reset. What's happening here?
