Hi!
I fear the latest security release of the SS 2.3 branch (2.3.9) has broken something related to DOM, since I’m getting the "Undefined index: start" in line 135 of DataObjectManager.php seen elsewhere when trying to edit files in Asset Manager, and a ImageDataObjectManager that has stopped working without errors (verified with my limited knowledge of the Firebug console): when I try to add a next image previously uploaded, I can select the folder, the Ajax icon turns a little, then nothing.
Has the 2.3 branch of DOM been updated to work with SS 2.3.9?
Best regards,
Juan
