I managed to install after second attempt on local (127.0.0.1) virtual host like http : //una  $sName as i was seeing in debugger yesterday ( do not already remember exact value) was something like html_tags.html, it did not contained '|' characters, that all was starting from view like 'home'.. Now I am on page like studio -> launcher my computer is Linux Ubuntu 18.04 server, so I have ff mpeg in /usr/bin/ffmpeg

I have new issue now: When i was doing Designer ->Cover or Designer -> Logo uploading image, it shows error for page like    una/image_transcoder.php?o=sys_cover_preview&h=4&dpx=1&t=1595269570
