Answer 1

In Chrome, open DevTools and go to the Network tab. Now click the Fetch/XHR filter. Then, click Publish and watch the Network traffic to see if any errors are being returned. That should give you an indication of where things are going wrong. You might see a 500 error returned on the Publish call.

Answer 2

I have solved This Issue by following these steps:

1, downloaded Backup of the website using a third party plugin 2, delete WordPress setup from the hosting side 3, install WordPress 4, put a backup file using a third party plugin 5, Boom starts working :)
