Clicking on “Preview” under a post in All Posts list goes to 404 Error

[Xtraboy]

If you click on the Preview link below a post name in the list of all the Posts, it takes you to a 404 Error page.

Clicking on the Preview button from inside the editing of a single post does work.

This happens with the Pitch, Drafts and Pending Review posts.

I'm having trouble reproducing this; can you let me know a specific post that you see it happening with?

In Drafts for example the first one “Content Migration – Beyond WXR”: ​https://wptv.wordpress.com/wp-admin/edit.php?post_status=draft&post_type=post On clicking preview the result page is this one ​http://wordpress.tv/?p=46618&preview=true and it gives me the 404 Error (Uh oh, someone made a mistake!).

And this happens for me on all the Pitch, Drafts and Pending Review posts.

It's still working for me. What browser are you using? Does it work if you temporarily disable all your extensions or switch to another browser? If you open the error console before visiting the page, does it show any errors after the page has loaded?

It’s working also for me now. I discovered about my settings in Chrome.
