What are the best permissions for a Wordpess install on Ubuntu managed by Webmin? Currently, root owns all the files and all of the files are also set to the root group. I'm using the virtual server GUI on Webmin to manage multiple virtual sites from this server. I'm wary of making permissions changes on a live server, and I'm worried that if I follow these instructions I might do something like deny Apache the right to access the Wordpress files.
Right now I just have /wp-content set to 777 to make plugin installs work, but I know this is not a good idea because any system user can edit the data. Are the permissions I linked to correct and should they work?
