I installed the plugin today (2.0) and really like the look of it. One issue I was having is that it is not refreshing and bringing up the latest feeds in fact it's been static for about 10 hours.
I read on some of the other posts in the forum that this may have something to do with cache plugins. I have disabled all of those plugins and it has not seemed to help. Is there another caching option on WordPress that I need to disable or is there some other issue causing the aggregator to fail to refresh?
