In Real-Time is a different kind of Instagram plug-in. Using the Instagram Real-time API, this plug-in is developed for users that want posts created
Don’t worry. There seem to be a couple of gremlins in the Instagram Real-time service from time to time. The In-RealTime plug-in compensates for this by requesting the previous 8 posts and checking to see if the images have been saved to your server. The missing post(s) should be created the next time you post to Instagram.
In addition, Instagram uses what they call the "2 second rule." This rule basically states that if your server consistently doesn't respond to the post-back within 2 seconds, the Instagram service will throttle back posts to your server to up to an hour. Unfortunately, there is nothing I can do to the codebase for this. If you are experiencing this issue, you may need a better host!
I’ve noticed that there are a few hosting configurations that cause issues with both writing the preferences and image files to the server. Windows servers and PHP in safe mode both seem to have issues, at the moment. I’m investigating a fix for these issues.
It appears as though the Instagram website, which is needed for OAuth and setting your token, doesn’t play well with Opera. Please use Chrome or Firefox.
