WordPress for Google App Engine has NO “Publish” Button

I want to use wordpress as CMS for my new project with Google App Engine. I followed this guide: http://googlecloudplatform.github.io/appengine-php-wordpress-starter-project/ and now I’m testing it locally. However I noticed that there is no publish sidebar with the “publish” button when I add new page or edit the sample page.

There is not even a “save draft” button.

I think I followed the steps carefully and there is no error on browser console. I believe it should be on the right side as seen on the dashboard on wordpress.com when you add a new page:

I found a workaround tho on how to publish. Whenever I typed in the textbox my work is then being auto save as a draft. What I do is go to the “All Pages” listing and do a “Quick Edit” on the page, I can then change the status from “Draft” to “Published” to publish that page.

But it would be very convenient if I can directly publish it once I finished, without going to the page listing and doing a quick edit. Can anyone help me with this?
