The above is a simplified explanation, but the following may be of interest and value to all, and also help expert users formulate their own solution to this problem.

<translate><!--T:19-->
* The file ''configuration.php'' is generated automatically in the site’s root folder (from ''configuration.php-dist'') during site installation and incorporates the site-specific information given during the install process. Changes made in the Global Configuration area in the site's administrative "back-end" are written to ''configuration.php'' when the either the ''Save'' or ''Save&Close'' button is used.</translate>
<translate><!--T:20-->
* Whenever Joomla! attempts to update ''configuration.php'' file it first attempts to make it writeable, and after updating the file make it unwriteable (i.e. read-only) as a security precaution.</translate>

* Files on the web server hosting your Joomla! site will be owned by one of several entities, depending on how they were placed or created on the server. Generally files on a Joomla! site will be owned by either of two user identities:</translate>
<translate><!--T:22-->
*# Files you upload by FTP or installed with FTP mode active will generally be allocated ownership of a user ID corresponding to your FTP login ID for that site,</translate>
<translate><!--T:23-->
*# Files installed from within Joomla! and with FTP mode inactive will generally be allocated ownership by the “phantom”  user ID that used to run the main web server processes as well as your Joomla! scripts (often named ''apache'' or ''www-data'').</translate>
