[SOGo] Problems with SOGo 3 Calendar

[f***@gmail.com]

I recently installed SOGO 3 on a CentOS 6.7 x32 test server with Nginx and
PostgreSQL 8.4. Until now almost every function works well but the calendar. i
can create tasks and dates but it does not show the month and when i click on
the event i've created as a test it shows nothing but and "bad gateway" error
on top right corner and blank spaces. I still haven't created any users except
the webmaster mail.
Anyone can help me to solve this? Has anyone the same problem? To see how it
looks you can see the images on this link:

Thanks in advance for any help you can give me.

UPDATE
To anyone who can help me to solve this issue, this is my server's sogo.log
file, i hope this make easier to find where is the bug. P.D. i changed the
domain name in the file.
