Upon upgrading to WordPress 2.8, everything looked like it ran okay. When I tried to log in, I had got an error the prohibited me from entering my WordPress Dashbord. The error I got was:
Fatal error: Call to a member function on a non-object in <path to my blog>/wp-includes/theme.php on line 387
I tried quite a few different things to get this fixed, such as disabling the plugins in PHPMyAdmin and even renaming the plugins directory itself. I then got a wild idea to rename the themes directory to something like “themes_old”. Upon doing that, my blog didn’t display (since there wasn’t a theme to display it) but I was able to access my Dashboard by typing in the URL. I then created a new themese directory and uploaded a theme to try and everything worked. My un-scientific conclusion from this is that the theme I was using , Connections Reloaded, was having some sort of issue with WordPress 2.8. Everything seems to be working as it should now, although I now have to look for a new theme.
