Hello,

You might want to follow these steps to troubleshoot your issue:

1. Edit your LinkedIn application.
2. Check Website URL, and JavaScript API Domains make sure they are the same as your site domain (http://www.yoursite.com and http://yoursite.com make a big difference)
3. Revoke and regenerate OAuth Keys
4. rw_nus must be checked
5. Go to the EasyBlog -> Autoposting -> Advanced Settings page and revoke the access.
6. Go though the EasyBlog -> Autoposting -> Step by step guide and re-enter the new keys and reauthenticate the LinkedIn access.

If the issue is still there, you can provide us your backend and Linkedin access so we can check this issue for you. Please give it a try.
