Custom Field - "Could not edit this item" issue
I have added a Custom Field for Projects with multiple options available for selection. Initially I had it set up as a drop-down menu. However, whenever I selected an option from the drop-down and tried to save it, a yellow banner with "Could not edit this item" appears along the top of the screen. I tried converting the field to checkboxes with the same result - I cannot seem to edit or change anything about the custom field. (I checked and the appropriate permissions/visibility are set up.) Any idea what this could be?
