After having updated my theme (Atahualpa),the widget is still there, it´s title too, but there are no more photos visible.
I have tried it by changing from "instagram profile" to the new options like "custom url), but it doesn´t work either.
I have deactivated the plugin and reactivated it - no display.
There are several new options for your widget, after this update of my theme - but it won´t work. Yet. Hope you can help me.
I prefer your widget as no complicated API setting (creation of an app?) necessary, and it worked well before.
