Whenever I create a child theme, it's never writable to begin with. Looking under Dashboard/Appearance/Editor, I get the message You need to make this file writable before you can save your changes. See the Codex for more information.
Using Filezilla, I navigate through httpdocs and then right-click over 'wp-content' and permissions are set to 777.
I'm a bit confused on what other permissions I should be editing. Any suggestions?
