Problem editing Subsite

[Sirman13]

Hi, I forgive for my bad English, I have a problem with mezzanine cms, it allows me to edit the main page (exallievidonbosco.it) but not the subsites created, for example, potenza.exallievidonbosco.it. It tells me the following error message: Sorry, an error occurred.

Any problems with permits? I made the mark of the subsite, just created, and the problem always reappears, where can I find the logs?
thanks in advance, Andrea
