Gotcha. Then the initial backend error was probably a token issue and was resolved after you logged in again and refreshed the channel.
Looking at the code, the link is not set properly after retrieving the posts, so when the stream module tries to display it, it just uses an empty link which will go to your homepage.
We have a hard time debugging LinkedIn as we've repeatedly tried to request access to the Developer Program but have been unsuccessful so far.
If you want to try to fix the link, can you try the following? In /plugins/jfbconnect/provider_linkedin/provider/linkedin/channel/company.php around line 181, change
//$post->link = self::getShareLink($this->provider->client, $data->id);
to
$post->link = self::getShareLink($this->provider->client, $data->id);
.
If instead, you'd like to remove the link, you'll have to do a theme override of /media/sourcecoast/themes/scsocialstream/default/linkedin.php. Line 23 and line 46 is what prints out the link.
