Hi,

1. Please go to Appearance > Widgets, find & then config the .Soledad Instagram Feed.

Go to https://pencidesign.net/penci_instagram/ get the token information then fill it out on the Instagram Widget settings.

2. All the Instagram Access Token is only available in 60 days, you must create a new token after that time: https://developers.facebook.com/docs/instagram-basic-display-api/guides/long-lived-access-tokens/

Regards,
