I’m experiencing the exact same error code today (since the update). But it’s not every domain for me.
I have 30+ domains across 5 different hosting packages (international hosting). Only the domains on my Windows based hosting are experiencing this issue. My other 4 hosting accounts (Linux) are fine.
All installations are on WordPress 4.2.2, and Wordfence 6.0.2. Some of the sites have the exact same themes/plugins too. Renaming the Wordfence plugin folder removes the error and allows access to the site/admin area.
Just wanted to confirm that the same is the case for me: only sites on Windows are affected by the update.
Same error… Site is offline.
Also got this error for a wordpress installation running on windows.
I’ve fixed this by adding the following function:

To:
wp-content/plugins/wordfence/wordfence.php
A much nicer solution would be to upgrade PHP to 5.3+ but that is not possible for me at the moment.
Hope this helps someone!
Version 6.0.3 is out. Please update and reply back as to your status.
