Auto posts


I have a listing website made with joomla and jreviews. I have it set to auto post new listings. The posts go through to shorten the URLs. My problem is that the posts make it to but they dont make it through to my twitter account. If I manually press the share button in than it posts to my twitter. My app that I created in twitter developer has read and write access to my twitter account, so does

I also tried another component to see if it would work and it does not auto post, again if I manually post from the component it works.

Why wont the auto posts work??
