After I changed image and clicked update, page loaded again with old image… in log file for apache was only script ‘/var/www/html/fog/management/ajax/dashboard.bandwidth.php’ not found or unable to start, so I searched forum found article fog-upgrade-from-0-3-2-to-fog-1-0-1-php-errors-centos-6-5.10680 so I decided to make new install again. And now its working fine (import hosts too).
I don’t know something broke in previous install, but everything in foginstall.log seemed ok.
Thank you for fog and your support!
