Ok, so I caused my own problem. I was testing autoblog and got aggravated that when I deleted and a feed, and the posts -- then setup the same feed again, it would tell me that there were no new posts.
So I deactivated the plugin and reactivated it.
But it still had a "memory" -- so I dropped the "wp_autoblog" table thinking that would erase the history and I could have a truly fresh install of the plugin.
But now I'm in no-man's land. It still remembers its prior installation, but no longer works properly.
I would like to remove all traces of the plugin and start over, but not sure how to proceed.
Thanks in advance!
