Using Softaculous, a new CMS(Content Management System) such as WordPress, Joomla, or Mambo has been installed on your website. It does not matter which CMS is installed, they all need to be able to write files on the server. However, they could show “permission denied” errors during the first-time setup or the first time an upload is attempted via their built-in web interface. This can happen when using DSO or CGI as the PHP handler. With either handler, php scripts by default run as the Apache user “nobody”, and the webserver software (usually Apache) needs to have write access to a user’s files to avoid this error.
