Hi,
I Installed "LoginFlows" Unmanaged Package in my (Salesforce OEM Edition/License) Sandbox instance.
After Security code verification when it redirects to Home Page an error page is showing "Invalid Page Redirection" with below Message:

"The page you attempted to access has been blocked due to a redirection to an outside website or an improperly coded link or button. Please contact your salesforce.com Administrator for assistance. For more information, see Insufficient Privileges Errors.
Click here to return to the previous page. "

When i Click the "Click here" link it goes to the Home Page.

But when i installed "Login Flow" Package in any development org it is working fine.

Can anyone help me out with this?

Thanks
