Since sometime around Wednesday I am unable to preview any new posts. When I select the preview button I get the following page: Not Found – Apologies, but the page you requested could not be found. Perhaps searching will help. This has become a consistent behavior. The post publishes correctly but not being able to check if links work correctly and such things is a real problem. Help.
Are you click the “preview” button on the far right hand sid of the page in the Publish module? Or are you clicking this link “Post draft updated. Preview post” above the draft post title display on a yellow background? I use the “Post draft updated. Preview post” link on the yellow background and it works well for me.
