I was attempting to update from the WordPress trunk, I believe, today. In the bottom right hand corner of the admin panel, you can see the following.
You are using a development version (2.7-beta3). Cool! PleaseÃ‚Â stay updated.
I click on stay updated and I get to the admin page for updates in 2.7. I had two choices, Upgrade Automatically or Download nightly build. I thought the Upgrade automatically would take care of the process for me and being as lazy as I am, I clicked it.
But alas, it did not work for me. I got the following scary error!
Fatal error: Cannot redeclare pclziputilpathreduction() (previously declared in /homepages/468/b1298473934/htdocs/r/wp-content/plugins/wordpress-automatic-upgrade/lib/pclzip.lib.php:5421) in /homepages/468/b1298473934/htdocs/r/wp-content/admin/includes/class-pclzip.php on line 5498
Apparently, it has something to do with the WPAU plug in and the folders? I’m not exactly sure since there isn’t anything pertaining to 2.7 directly, but at least I know I’m not the only one.
If I find anything else out, I’ll update this post. WordPress 2.7 will probably come out before I fix the problem though. I might try to upload a nightly build though. I’ve never done it, but it might be worth a try.
Updates – The Fix
Along with the comments below, I figured out how to update your WordPress 2.7. If you have the formerly wonderfulÃ‚Â plugin WordPress Automatic Upgrade, deactivateÃ‚Â it. Then proceed to update WordPress. It’ll work without errors. WordPress 2.7 introduces a new feature: no need to update by hand. So in otherwords, the WPAU plugin is no longer needed! (But thank you, WPAU plugin, for all of your hard work.)
