I always try to keep my blogs up to date and up until now I’ve used the WordPress Automatic Upgrade plugin.  A great little plugin that simplified the WordPress upgrade process.  Recently WordPress has added automatic upgrade functionality as a standard feature.

WordPress Automatic Upgrade Fatal Error

Today I was going about my daily blogging business and noticed that WordPress 2.7.1 was available.  I attempted to use the built in automatic upgrade and received the following error:

Fatal error: Cannot redeclare class pclzip in /home/mysite/public_html/wp-admin/includes/class-pclzip.php on line 171

Here’s what I did to try and fix my problem:

  1. I decided to try my handy WordPress Automatic Upgrade plugin instead, but it informed me that I was already up to date (even though I wasn’t).
  2. I next tried upgrading one of my newer blogs.  It upgraded just fine without fail.
  3. I did a little research on the internet and found that my faithful WordPress Automatic Upgrade plugin was causing the problem.
  4. I went to my plugins panel, deactivated WordPress Automatic Upgrade, and attempted the built in Automatic upgrade.
  5. It worked like a charm!

Now my blogs are all upgraded to WordPress 2.7.1.  One final note: I also read that if you do not have the WPAU plugin and you are experiencing this problem you might try disabling all your plugins then try the built in autaomatic upgrade again.
