Hello,
I've installed feedapi, and created a couple of feeds. When I go to mysite.com/feed-item/1234, where 1234 is the node id of one of the feeds, I get the full listing of the feed. I've observed that this is a view. When i edit the view, and make small changes (e.g. change the number of items that show up on the page, change from teaser list to full node), I see no changes in the views output. I am guessing this is because the default view is also occupying the url mysite.com/feed-item. I've then changed the url to feed-item1, and got tons of errors, like:

# user warning: Unknown column 'feedapi.nid' in 'where clause' query: SELECT count(DISTINCT(node.nid)) FROM node node LEFT JOIN feedapi_node_item feedapi_node_item ON node.nid = feedapi_node_item.nid WHERE (node.status = '1') AND (feedapi.nid IS NOT NULL) in /home/webadmin/mysite.com/html/includes/database.mysql.inc on line 172.
# user warning: Unknown column 'feedapi_node_item.feed_nid' in 'field list' query: SELECT feedapi_node_item.feed_nid, node.title, count( DISTINCT(node.nid)) AS num_nodes, feedapi_node_item.timestamp AS feedapi_node_item_timestamp FROM node node LEFT JOIN feedapi_node_item feedapi_node_item ON node.nid = feedapi_node_item.nid WHERE (node.status = '1') AND (feedapi.nid IS NOT NULL) GROUP BY node.nid, feedapi_node_item_timestamp ORDER BY feedapi_node_item_timestamp ASC LIMIT 0, 5 in /home/webadmin/mysite.com/html/includes/database.mysql.inc on line 172.

What I'd really like to do is create a block, one for each feed. However, I get an error stating:

user warning: Unknown column 'feedapi_node_item.feed_nid' in 'field list' query: SELECT feedapi_node_item.feed_nid, node.title, count( DISTINCT(node.nid)) AS num_nodes, feedapi_node_item.timestamp AS feedapi_node_item_timestamp FROM node node LEFT JOIN feedapi_node_item feedapi_node_item ON node.nid = feedapi_node_item.nid WHERE (node.status = '1') AND (feedapi.nid IS NOT NULL) GROUP BY node.nid, feedapi_node_item_timestamp ORDER BY feedapi_node_item_timestamp ASC LIMIT 0, 20 in /home/webadmin/mysite.com/html/includes/database.mysql.inc on line 172.

What am I doing wrong?
