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?
