    I’m getting this error when activating WPBruiser plugin at the top of all my site pages (latest 3.1.11 version):

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, '__return_empty_string' was given in /somedir/dir/public_html/wp-includes/plugin.php on line 173

    plugin.php line 173 is part of function apply_filters($tag, $value).
    I’ve tried to narrow down which call to apply_filters inside one of WPBruiser’s files is the one to blame, but can’t seem to find it.

    I’m using wordpress 3.5.1. The plugin page claim is compatible starting at wp 3.5.

    Any help would be appreciated.
