I am having the same problem, and the emails I have sent have not been responded to.
I resent the most recent one this morning.

I figured my problem out!
In the Discussions section under Settings – the default is to hold a comment if it contains 1 or more links…
I changed this to 0 and this change made posting by contributors work!
Good luck to others.
I’m having the same problems.
I tried uploading the above code into the functions.php , but it still isn’t working.
When a contributor posts a link through the link share option, the post looks as though it was successful, but doesn’t appear on the Activity wall or on any feeds.
Any other suggestions?
Thank you!
