Hi Daf,
I had tried to login to your website last week, once you said that you had 'Unique titles only' unchecked. But I guess, by then you had revoked our access to your website.
I have the same ABC Headlines news feed configured on my local setup and it is importing posts without any issue. So it is strange that it was not working on your website. I am not sure whether you tried the same feed at our demo site.
Regards
Chirag
