Hello,
I'm sorry, but we need more information for helping you, the blank page only means that there is some problem in the PHP code. You should either enable the error reporting on your server (or ask your web host to do it for you), or check your server logs to see what is the error encountered.
You can also send us the access information to your Joomla admin and FTP to
Tato emailová adresa je chráněna před spamboty, abyste ji viděli, povolte JavaScript
and we can check this directly on your server.
Best regards,
ARTIO Support Team
