Which files can I edit?
To help make our Managed WordPress plans as hack-proof as possible, we impose strict, security-oriented limitations on which files are editable.
As such, you will only be able to edit the following directories and files on Managed WordPress accounts:
/wp-content
wp-config.php
.htaccess
favicon.ico
You can also edit any directories or files you upload yourself, such as a php.ini file.
