Any got the SocialHub extra Instagram feed to work?

Hi,
Trying to get an Instagram feed to work using SocialHub?
When i click on the 'Get Instagram Token userid' i get an error...

Could anyone provide some steps to to get this working?
Thanks
Janice

There's some information here about authorization for SocialHub: https://modx.com/extras/package/socialhub

Thanks for your input.
I've attached a screen shot of my settings in System Settings. I wasn't too sure whether the Tags part was needed for the extra to work.
The part i'm a little unsure about is this:
Setup and run the SocialHub Cronjob located at /core/components/socialhub/elements/cronjobs/import.php
When i put that in the browser nothing happens.
Any ideas?
Thanks

Looking at the code, that cron job doesn't produce visible output, but should write something to the MODX Error Log.
