Please post the error logs as well.

I don't error in logs but when I inspect my navigator, files CSS and JS are not charged.

make sure that in your system lessc is installed. if not then please install with below command

sudo apt-get install nodejs nodejs-legacy node-less
sudo apt-get install npm
sudo npm install -g less
sudo npm install -g less-plugin-clean-css
sudo ln -s /usr/local/bin/lessc /usr/bin/lessc
sudo ln -s /usr/bin/nodejs /usr/bin/node
