I upgraded to the newest version of ACF. Now my ability to edit anything goes away when I click publish. The data is stored because I am able to display it on the front-end, but I can not edit again.
This is when I create a new group, all is well: http://i.imgur.com/S2arT.jpg
And this is when I click Publish, everything is gone: http://i.imgur.com/lhtNk.jpg
If I create a new ACF group, the data is saved and I can use the fields on EDIT POST, BUT when I click "PUBLISH" on the post, then this same thing happens and I can not access the fields for a 2nd time.
