I want to change some lines in conf file but I received that error:
"Failed to save configuration file : Failed to replace /etc/nginx/sites-enabled/sitename.conf with /etc/nginx/sites-enabled/sitename.conf.webmintmp.54793 : Operation not permitted"
Then I tried to chane permission of this file from here: etc/nginx/sites-enabled
But this time: failed to change permissions 256
How can I edit this file?
Thanks in advance.
