Hi @m-gbiorczyk
Please keep in mind that the Local JSON files will be created when you saved the field group. Could you please resave your field groups and see if ACF creates the Local JSON files?
If that doesn’t work, could you please try it with the default directory name (acf-json).
If still no joy, please make sure that your local server has the permission to create the files in that folder.
Thanks 🙂
