This one’s for all you Wordpressers out there. I came across this problem recently and thought I’d share the solution.

For a few days, in my Wordpress installation, when I clicked on the “one click upgrade” link on the plugins page to upgrade plugins, I was getting the following error message:

Fatal error: Cannot redeclare class pclzip…

I found that if you have the Wordpress Automatic Upgrade plugin installed, and it’s less than version 1.0, you will get that message.

Simply upgrade your Wordpress Automatic Upgrade plugin to the latest version and the problem will go away.
