I'm trying to put a feed on one wordpress blog that picks up feeds from another one that are about 'biodiversity.' All relevant posts are in the 'biodiversity' tag and category both. The feed works perfectly until I put in "filter="biodiversity" at which point I get nothing. There are plenty of posts about biodiversity but none are terribly recent, is that why it's not working?
Post is here: http://biodiversityontario.com/feed-sample/
contains [hungryfeed url="http://www.eco.on.ca/blog/" filter="biodiversity" item_fields="title,description,date" max_items="3" truncate_description=”100″ link_target=”_blank”]
Thanks for your help!
