Plugin-Installation is failing

  • Hello,

    i want to install a plugin on my 3.0.1 WordPress-Site, but it keeps failing:

    Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/x/y/xy.ch/htdocs/blog/wp-admin/includes/class-wp-upgrader.php on line 189
    Inkompatibles Archiv.
    Die Plugininstallation ist fehlgeschlagen.

    I have seen this error-message in ohter threads, but mostly after updating or moving installations. But I have not moved it. I have set it all up und worked on the theme. But the plugin installation is failing.

    What can I do?
