Blanco pagina after installation

being a new user, I tried to install the Joomla HUB package with the quickstart installation package. On a blanco website I uploaded by FTP and then created a new database. After that I could install Joomla as described. But after that, when I click on my website adress opens a blanco page; http://websitename/index.php/en/ ?????
Going to the administrator adres ; http://websitename/administator it works and I get acces to the administratore page .

Hi,

Please raise a new support ticket (top menu Support - Tickets) and provide us your website info, we will check it for you.

Hi Solidres, the problem is that I'am willing to test an installation on a testsite, without having to interfere with my actual website which is running on another websiteadress. So if I raise a new support ticket on my testadress, I'll loose the possibility to raise another support on the final websiteadress. Being a "HUB" subscriber only 1 domain is supported !!

Hi,

Please don't worry about that, we don't count test/dev domains.

Regards,
