This sounds like a permissions issue. Make sure that your Apache user and group has access to the file and directory that you are trying to modify.

  • in: /var/www/html$ls -la what should i do ? – Mohammed Al-Aazawy Apr 24 '22 at 21:05
  • @MohammedAl-Aazawy whats the output of `ls -l` inside your project directory? In Ubuntu I believe the default apache user is `www-data` so as a temp fix you could use `chown www-data:www-data ./* -R` **INSIDE OF YOUR PROJECT DIRECTORY**. Make sure you check to see who the current user and group is that way you can revert it back should something go wrong. – Ervin Šabić Apr 24 '22 at 21:09
