Hai,
I have completed installation of AC in my system successfully. But still when I try to navigate http://localhost/activecollab there's just blank screen. I changd the upgrade_check_enabled value to "0". And still I get the same error.
When I changed the debug option to True, then I got the following error:

"Fatal error: Uncaught exception 'OwnerCompanyDnxError' with message 'Owner company is not defined' in W:\www\activecollab\application\models\CompanyWebsite.class.php:64 Stack trace: #0 W:\www\activecollab\application\models\CompanyWebsite.class.php(45): CompanyWebsite->initCompany() #1 W:\www\activecollab\application\models\CompanyWebsite.class.php(49): CompanyWebsite->init() #2 W:\www\activecollab\application\application.php(21): CompanyWebsite::init() #3 W:\www\activecollab\init.php(125): require_once('W:\www\activeco...') #4 W:\www\activecollab\index.php(9): require('W:\www\activeco...') #5 {main} thrown in W:\www\activecollab\application\models\CompanyWebsite.class.php on line 64"

Please suggest me a solution to this issue.
