Updating from 3 to 3.01 Error

[mikew]

The issue is if your Mautic base url is set (by default) to https://mautic.yourdomain.com/index.php and you try and upgrade to 3.01 it does not find the update.php file.

The fix for this is setting your base url to root https://mautic.yourdomain.com/

Steps I have tried to fix the problem :
