The search in the forums are not working for me. I did a search for this statement, "If this file was writable you could edit it" and it returned no results. However, I found the statement on this page: http://codex.wordpress.org/Editing_Files
The issue I have is with CHMOD. I have read the above page but am not understanding what I permission needs to be set for the themes inside of the themes directory. All of my directories are 755. However, I'm unable to edit a file in the theme directory (sidebar.php). I can't set the files to 664. If I set the theme directory and the files underneath it to 777 is this not secure? Please advise which permissions I need to set to the theme directory and its contents. Thanks!
