Steps to reproduce:

1. Set a non-default Virtual Host for the Company (Control Panel -> Portal Instances) E.g.: test.hu
2. Add a new regular Organization "TestOrg"
   • Check the checkbox on the Organization Site (Create Site)
   • Choose Community Site for both public and private pages
   • Save
3. Assign the OmniAdmin to the created Organization "TestOrg"
4. Set a Virtual Host for the Public Pages of the Site of TestOrg e.g. testsite.hu
5. Access a Private Page of TestOrg through the Virtual Host of the Public Pages. E.g.: http://testsite.hu:8080/group/testorg/home
6. Go to Control Panel and use the back link

Result: http://test.hu:8080/group/testorg/home is opened (you should be logged in to test.hu to get the same result)
Expected: http://testsite.hu:8080/group/testorg/home should be opened
