Depending on when you did the “one-click” Wordpress install, it is possible that the problem discussed on the panel could have something to do with it. If the “one-click” install did not properly complete, your WordPress installation may be “broken”.
Are you able to see wordpress at all when you navigate in a browser to the directory into which you had it installed?
If not, it could be an indicator that there was a problem with the installation. If you can see the WordPress page, what happens if you click the “Login” link in the menu?
I’d be happy to take a look for you, if you share (or post in a PM) the url for your WordPress installation.
