dm albums full screen doesn’t work

Hi
I am using the latest version of DM albums. the full screen option doesn’t work. In fact – it does a strange thing. When I choose full screen it goes to a non existing URL – by doublung my domain name. The URL looks like this: ‘https://www.domain name/domain name/ …’
If I delete one domain name- ‘https://www.domain name/…’ than I can see full screen.
You can check it out yourself in here.

try selecting the full screen mode and watch the address. any ideas?
Thanks
Gury
