This plugin was working GREAT until this morning when I upgraded to 3.7.1. Now, on any page that I have a redirect set to go to, I get this error:
File "C:\inetpub\wwwroot//wp-admin/includes/post.php" doesn't exist!
I'm using IIS 7.5 and the Twenty Thirteen theme. Unfortunately, this is on a development server and I can't give you a URL to see. The error appears as plain text just inside the opening body tag.
