on /admin/settings/taxonomy_ezfilter in the 'Define filtered type' collapsible form, nothing is displayed under 'Node types:', just a red sign stating that i have not saved my vocabulary, or something similar.

If i save configuration anyway, the following Warnings are displayed:

    * warning: array_flip(): The argument should be an array in /home/kiteatla/public_html/drupal/modules/taxonomy_ezfilter/taxonomy_ezfilter.module on line 92.
    * warning: Invalid argument supplied for foreach() in /home/kiteatla/public_html/drupal/includes/form.inc on line 952.

and of course no taxonomy filter showing anywhere on my page..
