    Hello breakling,

    first I would thank you for your great work. At this moment I have a problem with your Plugin WP-PIWIK on my website. After installing and activating of your plugin, WordPress shows under the toolbar in the backend the follow message:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, cannot access private method wp_piwik::onPostStatusTransition() in /homepages/27/d526774006/htdocs/pbc/wp-includes/plugin.php on line 470

    This Warning Message will shown everywhere at the same position in the backend.
    At first, I searched for a few websites and was landed on:

    http://developer.infoymas.com/wordpress/warning-call_user_func_array-expects-parameter-1/

    At the end of this post I found the follow notice:

    PD: This error could be also related to plugins authors that declared a function on a previous version of their plugin and then on a newest version they delete it but forget to delete the action related.

    Therefore I write this post in your forum. Hopefully you can help me.
    By the way: if it is helpful I send you a private link to my website.

    Thanks for your help and please excuse my bad english.

    With kind regards

    This bug is already fixed and will be released with 0.9.9.11 very soon.

    Until the release, you can disable annotations to avoid the warning. Or disable WP_DEBUG (if it is a live system, you should disable debugging always).
