HybridIgniter LinkedIn login error

[ansin218]

I am using this plugin in my codeigniter project.

https://github.com/andacata/HybridIgniter

I have set up the application on LinkedIn page. However, I keep getting this error:

User has cancelled the authentication or the provider refused the connection.

The log file also shows there were Invalid tokens.

After Googling, I found LinkedIn had undergone a change in their API stuff. And that the plugin I am using uses OAuth 1.0 where as I do not find any such settings in LinkedIn app page. I only find Client ID and Client secret. And hence, I am not able to use the correct matching tokens/keys. How do I find them from LinkedIn application page?
