I installed LAMP and WordPress on my system a week ago. Since I couldn't create Child Themes in WordPress and work with PHP folders for my other projects collocated in var/www without using Nautilus I wanted to solve the permissions issue.
I hoped to bring a solution carrying out the commands on this page for my WordPress folder: http://wiki.apache.org/httpd/FileSystemPermissions.
This allowed me to play with any file in the folder like creating and modifying .css files through WP Admin, etc. But after a restart I discovered that I can't change DNS settings of my network connections in the list anymore because it is asking me the root password and even though I enter the password it doesn't let me do the action giving "insufficient privileges" error.
Can you help me correct the mistake I possibily made during the configuration and, maybe, configure again the permission and ownership settings for var/www/somefolder as it is adviced to be configured under general circumstances?
Thanks in advance!
