change permissions with Chmod
Use Chmod in the terminal –
To change all the directories to 755 (drwxr-xr-x):
find /opt/lampp/htdocs -type d -exec chmod 755 {} \;
To change all the files to 644 (-rw-r–r–):
find /opt/lampp/htdocs -type f -exec chmod 644 {} \;
Go to a directory such as htdocs and do this –
sudo chmod -R 755 /opt/lampp/htdocs
