Bikestore - quickstart package not functioning

After installing the package (gk_bikestore_quickstart_J!3.zip), available only to the admin panel. The main page is missing - blank page in the browser. Tested on a virtual machine and on a real hosting.
How do I fix this invalid package and install the demo data?

Hi,
please make a small test:
change default template from gavick to joomla protostar for front-end and check.

Did you have any red/error marks in server settings during installation
Did you tried any other QS before on this same server environment?
Or maybe "naked" Joomla downloaded from joomla.org.

I think there might be a server settings problem case.

Thank you for your attention.

Yes, Beez3 and Protostar templates are displayed correctly.
No errors during installation - everything goes normally.
Tested on a virtual machine LAMP "turnkey-lamp-13.0-wheezy-amd64-vmdk". Was also tested on real hosting (Zenon)

P.S.
I would like to add, maybe it's important:
This virtual machine LAMP correctly matches the settings, available to me hosting providers (Zenon, Agava - in RU domain).

Try to use JAMP (standalone server) - you can try trial version as well.

Please, before you'll send "green men" change one settings:
in global configuration set showing errors to Maximum - and check what error message you will see on front-end
