I feel like a real idiot.
I need to let someone change the order of photos in a multiple galleries.
I have the instructions here:
but it says, "Make sure to select the Menu order option in the settings".
Where is that setting???
At the top of each gallery in the edit screen it says "order" but there is no field with which to change the pictures beneath it and I don't see the option to turn this on anywhere in the "gallery settings".
I feel crazy.
