I have just upgraded to 2.5.1. Now, when I edit a page and click the preview button, the page shows fine. But when I publish or save the page the page will use what I think is the attachment.php file to display the page. All the content that is supposed to be on the page will not show up. I've tried changing the template, but this would not do anything. Also, the page will have comment boxes enabled, although I've turned off commenting for this page. I have no clue on how to troubleshoot this. Suggestions please?
