Upfront doesn't let me open a saved page.

Hi, it seems Upfront yet needs some improvements to run smooth...
I set up it on 3 different servers and configurations, and I had some kind of problem everywhere (check the tickets).
Now I have this problem with this page: http://lecascatedisaturnia.com/come-arrivare-saturnia/
if I try to open this page, it hangs on the "wait" icon indefinetly...
I've got you dasboard access to check it
