Q:

Second user cannot Publish to Timeline

Sorry in advance - I've just been following tutorials and have spent ages on this trying to get this to work, but I have a fairly limited knowledge of the development side of Facebook!
I have created an App with the Open Graph settings set with the standard Read and Article as action/objects I will use for my website. I have tested a button "Post to Timeline" on an article page and it works, fantastically. However, when I forward it to my friend (who I have made a developer) and she clicks the button, she gets the following error:
"(#3501) User is already associated to a article object on a unique
action type Read. Original Action ID: (10150563976761680)"
How do I avoid this? Is the access token exclusively applicable to me? Or is it because it's still pending submission?

A:

Check the settings for your Open Graph action.

Go to the Open Graph Dashboard for your app on Facebook Developers.
Click on the Read action.
Click the Advanced link.
Make sure that Allow Multiple is selected for the setting called Unique action.

(or simply Read another Article)
