I am having the same problem. GoDaddy said, unless I misunderstood, that the hosting I have is fine to support the WordPress application, but I have been having problems since yesterday. I went through all the troubleshooting documents I got, and still nothing. I even uninstalled it and reinstalled it, went into the mySQL database and made sure everything was fine and still, nothing. GDHosting, or if anybody else can help (besides of course just saying don’t use GoDaddy ?? ) that would be so awesome.
