Vtiger crm 6 module=Users&action=SystemSetupSave

I working with the installation vtiger crm 6 in a server with PHP 5.2.7,on each time when i login the url is stuck with this page module=Users&action=SystemSetupSave.
  
I was facing same problem and this was due to some header path which need to change .
open login.php file under

vtigerCRM\modules\Users\actions

now

about 48 line in the code
find
header ('Location: index.php?module=Users&parent=Settings&view=SystemSetup');


change this line to

header ('Location: index.php?module=Home&view=DashBoard'); and upload this at your server.
the problem will resolved
