[support] Help migrate a site

Hi, I need some help to migrate a site.. If I move it using ftp and scp and changing the config file work, but something don't go. If you can go to http://www.acofiin.eu/ you can see the error (I put the display_error = on in php.ini) I tried rebuild the php, mysql and everyone in the linux platform, I tried to move the site to enother domain, clean the cache, but nothing.. I have always that error: *Parse error: syntax error, unexpected '?' in /var/www/vhosts/ acofiin.eu/httpdocs/includes/common.inc(1477)<http://acofiin.eu/httpdocs/includes/common.inc%281477%29>: eval()'d codeon line 21* Can someone help me? Thank's ---- Carlo Filippetto
