I extracted the MediaWiki to my web-site, renamed the directory to wiki and browsed to it. I then clicked on the config link which took me to mywebsite/wiki/mw-config/index.php, but the resulting page is blank. What am I supposed to do to configure the website?

Check the error log and report your findings please.

I checked the web-site error log and the most recent message was from May 3rd. There was nothing relevant to this failure.

When I modify index.php to enable display of error messages I get the following:

Fatal error: Class 'DOMDocument' not found in /var/www/html/test.zipdandy.com/wiki/includes/cache/localisation/LocalisationCache.php on line 663

When I attempt to fix this according to the documentation I get the following errors:

 You could try using --skip-broken to work around the problem

 You could try running: rpm -Va --nofiles --nodigest

Obviously I do not want to install the PHP 5.3 version of php-common on a PHP 5.6 system. This is on centos6 by the way.

I tried the following:

bash-4.1$ sudo yum install php56w-xml

-bash-4.1$

but I still get:

Fatal error: Class 'DOMDocument' not found in /var/www/html/test.zipdandy.com/wiki/includes/cache/localisation/LocalisationCache.php on line 663

Run sudo yum remove php-common

Note that after installing, you need to restart apache so it picks the installed extension.
