What is true chmod for WordPress?

Question

For all the folders and files.

Please give some explained answer.

Answer 1

All files should be writable only by your user account. So the correct permissions for files and directories are:

• Directories: 755
• Files: 644

You may want to secure some files:

• wp-config.php: for maximum security, this file should be made writable by your user only or its group. This means 400 or 440 permission
• .htaccess: 666 permission, so that WordPress can automatically generate rewrite rules for you
• wp-content/: some plugins and themes may require write access to this directory. you will be prompted when necessary.
• wp-content/themes/: 664 permission if you want to use the theme editor
