I did a fresh install and although we lost a lot of info everything works fine now.
I had a similar problem!
I had P2 installed and was happily using it when I saw that an upgrade was available. I upgraded, and now when I load the site it is completely gray, with NOTHING showing up. I tried using other themes and they worked fine. I deleted P2 and then went back and reinstalled it and got the same results. A blank gray page. Oh no! How can I fix this?
Please please please help! I love P2 and use it to group blog with my students. They love seeing their picture beside their posts!
