Cannot View/Edit Pages No Site Load 2.6 or 2.7

My original post:
I loaded WP 2.7 this morning on a completely new domain. I am having trouble editing pages. I seem to be able to create a page, but when I try to edit it I cannot select the page. The pages are registering in the menu, but when I click to select a page it will not display. I’m suspecting that there is a plugin interfering, but I don’t know.

Here are the plugins I have installed.

I then downgraded to 2.6 figuring that perhaps it was something with 2.7, but it isn’t. I am still showing the screen that indicates there are pages, but says “No page found.” Here is the screenshot.

Finally, I can load the site from my control panel through “Visit Site” in both 2.6 and 2.7, but cannot call the site by simply typing the site name into the browser. I’ve tried IE and FF 3.0.
