I checked, * is selected for all sites.
I have one new info:
The other guy that works on the server told me that he changed some lines in /etc/apache2/sites-available/default file...
I checked there, but it looks like it's ok, maybe some options there are misconfigured, can i found somewhere original file? i checked on the system, doesn't exists.
