Nevermind. I figured it out; I had to permanently delete the other pages I had previously created for the same purpose. Once they were gone it fixed the problem. Thanks for your help.
Thanks for your response Sanjip. It turns out there is no page with an id of “20”, despite the error link. (The page where I want my posts to show has the permalink: http://www.proconciliation.com/?page_id=183.) I don’t know how to reconcile. Further help would be appreciated. Thanks!
