Bareos webui - The requested URL /bareos-webui/dashboard/ was not found on this server

Do you have any experience with Bareos on Readynas  OS6? Everything works perfect except bareos-webui. I set Apache alias  /bareos-webui /usr/share/bareos-webui/public/, so default login page will be displayed, but after login redirect me to MYSERVER/bareos-webui/dashboard/ with this: The requested URL /bareos-webui/dashboard/ was not found on this server. There is complicated Zend Framework with many php modules, not simply structure to which I can make Alias.
