This issue is not limited to our themes alone and is a new widespread problem for all Instagram feeds used throughout the web. It appears to be a bug within Instagram API following a change within their own software to include a mixture of both horizontal and vertical images within a multiple image post.
We expect this to be resolved quickly and are awaiting feedback from them at this time.
What can I do?
The best practice is to use images that are the same aspect ratio when publishing on Instagram, this will ensure that you never see issues with your feed images.
If you can not avoid using different sized images we recommend temporarily disabling your Instagram feed using your theme options and re-enabling that when Instagram have fixed the issue.
