Hi @modifly
ACF deos not contains a hook which disables / enables the sidebar attachment details. I’m not sure what the solution to this issue is.
The WP 3.6 uploader has been an extremely tough and troublesome update for ACF, and in short, I’m not sure how to get these options to appear in the sidebar.
What does the sidebar retina options look like? Can you use the WP media library pages to add the retina source?
