Thanks for the reply @johnny: as i said i have imported the vm, how can i missed the hidden .git directory? In any case i've checked inside /var/www/html/ and this is the content
root@itflow:~# cd /var/www/html/
.git/    api/     dist/    models/  portal/  vendor/
.github/ css/     js/      plugins/ uploads/
and inside the folder .git/
root@itflow:/var/www/html/.git# ls
HEAD      config       hooks  info  objects      refs
branches  description  index  logs  packed-refs
Is there something wrong?
