Okay I returned back to previous version by restoring VM of Moodle back and version is 2016120501.09
Only problem is before making this backup I just go to admin settings and updated plugins - > so still Google Auth button is not showing in main page to click.
But I am in Moodle 3.2 so how to make it show again or shall I downgrade Auth plugin ?
THis is Moodle Version in Config File in Database 2016120501.09
