WP | The background PHP script cannot be modified and the server cannot write the problem directly.

Problem description

1. When trying to modify the footer, found that the WordPress background appearance (appearance) option does not have the editor (edit) Sub-option, after the settings modified and found unable to save.
2. An attempt was made to install the plug-in, but could not be installed directly, presumably because the server prevented other users from writing.

Solution Solutions

1. Appearance-the edit option is not, just modify the definition of the relevant parameter in/etc/wordpress/wp-config.php. For example, in my background of this file, only need to modify define ("Disallow_file_mods", false); Can.
   The reason why cannot save, write, is the file (or directory) permission problem, as long as chmod can.
2. Plug-in direct installation, as long as the wp-config.php file in the last add the following code can be define ("Fs_method", "direct");
   Define ("Fs_chmod_dir", 0777);
   Define ("Fs_chmod_file", 0777);
   Then modify the/usr/share/wordpress permissions for 777:chmod-r 777 WordPress.
