thanks for this report. This issue will be fixed in our next release. In the meantime consider using your Instagram-Username instead of “self”. Thanks!
Please use or userid instead of your username: [instapress userid="1128788" piccount="4" size="75" effect="fancybox"]
Thanks in advance, we’ll fix this soon!
By the way, did you register your Instagram application on your user?
If the above solution still doesn’t work, try resetting the application in Instapress settings and set it up again.
Just a quick docs request. Awesome plugin! Would be nice to use not only by shortcode, but if under “Usage” you might also describe the function for adding it to a template file.
