As I saw from your forums posts, you encountered strange behaviors in the site in the last few days. We are actually upgrading and doing some changes in backend framework, and like in many things in development, we are experiencing some things that affects applications initially we didn’t suspected that they’ll be affected, but we resolved that already.
Hopefully all of the other issues will be resolved in the following week, and then we’ll be able to come out with the new framework.
BTW, The only indication that you will see as indication to the new framework, will be a change in the content URL structures. 🙂
