    It doesn’t work the command you gave me.

  • If you find where those directories are located (The ones in the red box on and do a chmod 777 on each one of them, for example (Assuming they are located in /var/www/html:

Hi there,

To change file/folder permissions you’ll want to use the chmod command:

chmod {options} filename

For example the below will grant the owner of the file (referenced by u) write permissions (referenced by +w) on the file example.txt:

chmod u+w example.txt

You can also use binary references to set file permissions for all users. For example the below will give the owner & group that the file belongs to permissions to read, write and execute (Read = 4, Write = 2, Execute = 1), whilst anyone else will only be able to read the file:

chmod 774 example.txt

The following link fully explains file permissions and the respective commands that can be used to control this:

Hope this helps!
