Fatal error: Cannot redeclare pclziputilpathreduction() image

If you've tried upgrading a recent version of WordPress and received this error…

Fatal error: Cannot redeclare pclziputilpathreduction()

…here's what you do.

In a nutshell, deactivate the plugin “WordPress Automatic Upgrade”, then try again and WordPress should upgrade without a hitch.

Here's the explanatory video I posted on YouTube about this error, and how to fix it.

Setup Unmanaged VPS (4 Noobs!) ... with vpsBible
Secure WordPress. Properly. ... with wpCop, the platform's dedicated security website
Olly 'the_guv' Connelly's vpsBible.com site and 'WordPress 3 Ultimate Security' book.

About Fatal error: Cannot redeclare pclziputilpathreduction()

The reason you get this is because your activated plugin, WordPress Automatic Upgrade, is creating problems with WordPress' new in-built automatic upgrade function. But because of this new WordPress feature, you don't need this plugin anymore, anyway. It was a great, highly useful plugin. But it is now negated, so lose it. And then, no more error. Upgrade away.

Did this fix work? Or not? Hmmn! Lemme know below…
