Multisite – subsite – Select group in widget shows no groups

Hi,

I’m using latest version of everything.

When activating the widget on a subsite of a multisite environment, the widget can be draged in the widgetbox. But the dropdown menu of selecting a group remains empty. No options/groups to select. Output on my FrontPage is this (pure plain tekst):

ACF Key:
widget_acf_widget_3

Fields:
Array
(
)

Use get_field(“fieldname”, $acf_key); to get the fields in the widget function.
