Automatic Upgrade Fatal Error

[pianoguy91]

In attempting to upgrade to the most recent version of Wordpress, I encountered this error.

Fatal error: Cannot redeclare class Plugin_Upgrader in C:\wamp\www\latestWP\wp-admin\includes\class-wp-upgrader.php on line 582

I am running the alpha version on my local machine, but based on the error, it seems that the error is in the codeflow, not the version.

How did you trigger the error?

Had version 3.0-alpha early installed? Hit upgrade core, that error came up instantly? Or did it start to upgrade and then error out?

I'll do some test upgrades later and see if i can duplicate it.

This line is function plugin_info()

Have you tried to do that with plugins deactivated?

Just to try to locate the error better.

dd32 - When I hit upgrade core, the error did come up instantly.

bi0xid - It turned out to be a plugin. I will contact the plugin author with the error for a bug fix.

No error anymore.
