Yikes. Just upgraded from 220.127.116.11 to 2.1 and am getting a blank index page for my site (It's built heavily with more-types calls.)
I'm finding this in the error log:
[04-Sep-2011 02:39:54] PHP Fatal error: Call to a member function add_cap() on a non-object in /home/rchseagl/public_html/wp-content/plugins/more-types/more-types-object.php on line 139
Any idea what's up?
