This seems to be an incompatibility issues between WordPress and Jetpack.
When I activate Jetpack and connect to WordPress for stats, my posts either do not show, or they only show the title, then stop.
I have repeated this several times with all other plugins deactivated, and results are the same. I have also deleted Jetpack and reinstalled it, and reinstalled 3.7-RC1-25851. This is happening on all of my sites where I have 3.7-RC1-25851 and Jetpack, but not on my other sites that are on 3.6.1
As long as I do not connect Jetpack to WordPress, I can activate Jetpack and all is well. Once connected to to WordPress my posts either quit showing or only show a title.
Anyone else seeing this?
