My Dashboard > Right Now panel says I'm running version 2.7, and it says version 2.7 in the bottom right of the page as well.
But when I click on the Tools > Upgrade page, it says "You have the latest version of WordPress. You do not need to upgrade."
It gives me options for a re-install automatically and a download, but clicking the first one simply refreshes the page and removes all it's text but not the menus, etc (!) and the download refreshes the page and does nothing.
Where do I start trying to fix this? I'm pretty sure I'm still running 2.7 in spite of what the Upgrade page says.
