Bug? Cannot redeclare a pluggable function (4 posts)

    I just upgraded to 2.8.2 and now a plugin I wrote has broken:

    Plugin could not be activated because it triggered a fatal error.

    Fatal error: Cannot redeclare wp_authenticate() (previously declared in [...]/wp-includes/pluggable.php:456) in [...]/plugins/myplugin/login.php on line 64

    Is this a bug? Or am I doing something wrong?

    For now I've just commented out wp_authenticate in pluggables.php, but that's not a very good solution!

    Did you get this figured out, Harry? If so, would you please
    share the solution with the rest of us who are having the same problem?

    When a plugin goes through the activation process, it gets included *after* pluggable.php gets included. During the load process, it gets included before.

    Any plugin overriding a pluggable function should take care to wrap their function definition in a function_exists check, not only to play nice with the activation process, but also with other plugins.
