JFBConnect login with linkedIn not going through

Alex,
Yesterday I moved the site to https. maslowed.me
Today I am getting the following error on LinkedIn login: I think you can also see it on our site.

Error code 400 received requesting access token: {"error_description":"missing required parameters, includes an invalid parameter value, parameter more than once. : Unable to retrieve access token : appId or redirect uri does not match authorization code or authorization code expired","error":"invalid_request"}.

I never had this error earlier,though I had once seen a 404 error (I mentioned in another post).

As the site is live and being taken to end customers: I need the solution as soon as possible: please help.

Best,
Pawan.

Hi,
I saw the linkedIn update: developers.linkedin.com/blog/keeping-you...t-practices-security
It mentions two changes
- Header-Based OAuth 2.0 Authentication
- Secure URLs: Over the next few weeks, our APIs will begin returning HTTPS URLs.

Do we need any changes to be done in jfbconnect for meeting these requirements?

The login works fine if I dont try to get the profile details after login.
If there is any reason why 400 may come on trying to get profile just after login, please tell.
