Support › General › lock custom field changes
Hi! Can i prevent changes of a custom field by role?
1. Administrator set a custom fied
2. IF custom field is set, author cannot change the field
I this is pretty clear.
(Not sure if exist option to lock field in metabox)
Do you mean prevent changes in the field group? If yes, there isn't an option to do that. Any administrator can edit a field group. If you don't want a user editing a field group, please set them as Editor.
