Incorrect user ID specified

I was also seeing this issue and I believe it appears when too many requests are made by the same application (client ID). This is what I was seeing when making a direct request to the Instagram API:

{“code”: 429, “error_type”: “OAuthRateLimitException”, “error_message”: “You have exceeded the maximum number of requests per hour. You have performed a total of 12871 requests in the last hour. Our general maximum limit is set at 5000 requests per hour.”}

To solve this I replaced the client ID in the request with one from a new application created in Instagram (rather than the one included in the plugin).

If the above is correct the plugin should just need to provide the option to specify a Client ID. For now I’ve had to overwrite the one hard coded in basic-instagram-widget.php line 111.
