Images from someone else's account are now appearing in the widget

Thanks for the great plugin. I’ve been using it for a while to display my instagram photos from my account with the username “migrantp”. Here’s my profile: https://instagram.com/migrantp/

At some point recently, the widget has instead started picking up photos from a different account, this one here: https://instagram.com/__.migrant.__pv_/

The configuration of the widget has not changed and it’s still set to “migrantp”. You can see the behaviour here on our website: https://waywardlovers.com

Thanks for your help and let me know if you need any more information.
