Blank Screen after installing WordPress 4.4.2

Installing or upgrading to WordPress 4.4.2 on Apache results in a blank screen.

Updated: 3/14/2017

Symptoms:

After installing WordPress 4.4.2 on an Apache Server, the screen displays a blank screen.  If you check the Apache server error logs you will see the following:  PHP Parse error: syntax error, unexpected ‘[‘ in /var/www/vhosts/”Your Site”/wp-content/install.php on line 66.

Solution:

You are running an incompatible version of PHP, the server PHP level should be at PHP 5.6 or higher. This is required in order to run WordPress 4.4.2, to resolve this issue upgrade your server’s PHP to the latest version.  This should be done anyway for security reasons.

Problem: XMAP displays a blank screen when you click on the sitemap in Joomla 3.2.* and higher, or it displays a Internal 500 error.

Solution: XMAP references a component that is no longer required in versions later than 3.2.*

Remove or comment out the following line from /components/com_xmap/helpers/xmap.php

REMOVE OR COMMENT OUT:  require_once(JPATH_SITE .’/includes/application.php’);

It should be in the top 7 lines of the php script.
