roelb on "[Plugin: Simple Instagram Widget] Error Message - No Sandbox User"

I updated Simple Instagram Widget recently. After that, it did not show any images anymore.

I tried to reconnect with Instagram but got the following error message:

{"code": 403, "error_type": "OAuthForbiddenException", "error_message": "You are not a sandbox user of this client"}

Website in question: http://soulsistermeetsfriends.com
Instagram-Useame: soulsistermeetsfriends

What can I do to get the Plugin working again?

Having the same issue. I think something changed on the 1st of June to the instagram API and the plugin needs to reflect those changes.
