I see that CustomPress 1.3 has been released and has export / Import capabilities ... Woo Hoo!!!
I updated on one site of mine and the Export / Import menu shows up but on another site I installed 1.3 on the menu doesn't show up: ScreenShot
To test that there wasn't a conflict I disabled all other plugins. The issue still exited. I then uninstalled CustomPress and reinstalled it. Even with all other plugins disabled I still am not able to see the export / import menu item.
