I tried to edit an existing page in my business site (WP 3.3.1), but the Redirection plugin keeps redirecting /wp-admin/post.php when I hit the update button, despite the fact I did not create any redirects for this URL. No matter what settings/options I use, this keeps occurring. Even when the plugin is disabled, it keeps doing this.
This was not a problem previously. Is the plugin broken? I don't see any updates since October 2011, so it is recent orphanware?
How do I fix my site when I can't edit it now? :-(
