4.6.10 to 4.7.1 upgrade woes
I got CiviCRM to come back by manually entering the paths manually into the CiviCRM Settings Overrides in civicrm.settings.php file.  There were some more error but at least CiviCRM came back for me.  It is obvious that the Reset Paths is causing problem and it might have to do with the way UpdateConfigBackend is calling a URL for GettingStarted.php.  I am not a developer but they all seem to be linked.  I shared what I actually did in this posting at the bottom: 4.6.12 to 4.7.1 upgrade causes problems with directories, update paths and clear cache
