Hi Tigran,
Thanks for your answer.
Well, there is not much ‘Feed ID’ I can select in the widget menu: there is a drop down menu called ‘Feed’, which only contains one point called ‘Impressions’, which is the name of the feed I created in the ‘Instagram Feed WD’ menu.
I already erased the feed and created new from scratch a couple of times. Still getting the error!
Already tried around with the plugin some weeks ago and everything worked fine. Yesterday I updated though…
Thanks!
