Thread:Project:Support desk/MediaWiki returns a blank page after install.

I am using MediaWiki 1.19.2. PostgreSQL 8.4.12 and PHP 5.3.3.

I am getting the following error from the error log.

[Tue Sep 11 11:36:50 2012] [error] PHP Warning: require_once(/var/www/mediawiki-1.19.2/LocalSettings.php) [function.require-once.html]: failed to open stream: Permission denied in /var/www/mediawiki-1.19.2/includes/WebStart.php on line 134

[Tue Sep 11 11:36:50 2012] [error] PHP Fatal error: require_once [function.require.html]: Failed opening required '/var/www/mediawiki-1.19.2/LocalSettings.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/mediawiki-1.19.2/includes/WebStart.php on line 134

As a preliminary matter, I have already read prior articles and possible solutions to this problem. That includes changing permissions on LocalSettings.php using chmod 644, 755, or 777. I have also attempted to change ownership of the file using chown to apache which is the user name on the Apache server. None of these solutions has fixed the problem. Anyone have other suggestions?
