/tmp/www not created on Turris Omnia (finished with missing config4.0.js)

[zdposter]

I used yamon3.4.7 sucessfully.
I just want to upgrade to yamon4 version. After running instal.sh (4.0.7 version) and finishing setup, yamon gui is not running.
Fist check shows that e.g. /tmp/www directory to is not created...
So I created it manually, run setup.sh once again and... nothing happens: /tmp/www is empty, http://192.168.10.1/yamon/ shows "404 Not Found"...

So I created manually symlinks as shown in http://usage-monitoring.com/v4Install+Validate.php
I did not find config4.0.js, so I run install.sh once again... /tmp/www/js/config4.0.js was not created (only live_data4.js)
Is there any way how to create it? Or how to convert config3.4.js to config4.0.js
Is there any tutorial e.g. how to manually install yamon4?
