Sorry for the delayed response. I just saw that you had sent an email to us and your credentials via Private Message.
I was just able to get into your site to investigate further. The reason you can't authenticate with LinkedIn is because your servers time seems to be off by a few minutes. Generally, JLinked should automatically detect this and correct this problem. I'm not sure why it's not able to on your site. When I enable the "Display LinkedIn API Errors" setting in JLinked, the following message is shown on the front-end:
JLinked Notice: Server time not in sync with LinkedIn. Setting correction offset to: 78s
For some reason our correction isn't working.
The best solutions to fix this on your site would be:
* Adjust your servers time forward by 78s.
* Enable NTP on your server, which is an automatic time synchronization function that will ensure your clock never gets off by too much in the future.
Please let me know if that helps,
Alex
