[Vtigercrm-developers] Installing vtiger with an old session

[Alan Bell]

it is also here http://code.vtiger.com/vtiger/vtigercrm/issues/56 with a 
suggested one line patch, change line 39 of includes/main/WebUI.php to

if ($userid && 
vglobal('application_unique_key')==$_SESSION['app_unique_key']) {

so that it checks that your session is one for the unique key of the 
instance. I am not sure if there is a better way to do it, but this 
should work whatever your apache settings are.
