LinkedIn again - All Sites

Hello,

We are having issues with revoking LinkedIn and sending posts out. Neither the button, nor database table being deleted does anything, but the icon lights up.

I've provided credentials below:

Please push the latest blog out to LinkedIn as a test.

Also mention to us why this button is not working, never has to revoke on any site and also the fix to this, so I can apply to other websites we run.

Thanks
