I have an issue with an old build.
EE 1.6.8 - Build 20090723 Matrix 2.0.11 Playa 3.1.2
I create the matrix field fine, but if I add a playa segment, after saving the field, I can no longer access the field. If I click on the field label to edit it, I am shown nothing but an Update button. I can not edit the field in the entry template either. I need to get this fixed until I get everything rebuilt and updated to 2.
