I've just completed an upgrade from 2.6.5 to 2.7. Most everything works but I can't see a list of my old posts. I get an Internal 500 Error (please try again later). Also I am still seeing a message - WordPress 2.7 is available! Please update now - even though in the Dashboard it shows that I am running 2.7
Funny thing, after the install - I didn't even see anything in the Dashboard (left Pane).
I did everything according to the install instructions for an upgrade - deleted the old wp-admin and wp-include folders. Then deleted all the php files in the site root and manually created a new wp-config.php. I ran the upgrade.php and everything looked to be ok. However, the site is working but I can't see my old posts. I can however look at the Pages defined in my site.
Anyone have a clue what I should try next?
