I'm sorry for the delay and confusion. We used to have an affiliate program for our products, but we discontinued that in January of this year. It seems like Stack Ideas (developers of Easy Social) have not updated the link in their extension yet, which is why it is leading to an error page.

I hope that helps answer your question, but should you need anything else, please let us know.
Thanks,
Alex
