    When click into my Plugins on the new dashboard I receive this message:

    Site #1:
    Fatal error: Cannot redeclare uninstall_plugin() (previously declared in /www/xxx/docs/wp-admin/includes/plugin.php:509) in /www/xxx/docs/wp-content/plugins/pluginstaller/uninstall.php on line 89

    Site #2:
    Fatal error: Cannot redeclare uninstall_plugin() (previously declared in /home/xxx/public_html/wp-admin/includes/plugin.php:509) in /home/xxx/public_html/wp-content/plugins/pluginstaller/uninstall.php on line 14

    Site #3:
    Fatal error: Cannot redeclare uninstall_plugin() (previously declared in /home/xxx/public_html/wp-admin/includes/plugin.php:509) in /home/xxx/public_html/wp-content/plugins/pluginstaller/uninstall.php on line 89

    For obvious reasons I have changed the web addresses to xxx. This is happening on several of my WP sites. Help?

    In short, the plugin is not compatible with 2.7.

    It's because of a change that introduced the "uninstall_plugin" function to the WordPress core.

    You have some kind of plugin called "pluginstaller". It's interfering with the new built in plugin installer functionality.

    Remove that interfering plugin.
