Joomla: 1.5.x
JoomFish: 2.0.4
Just change the modules/mod_poll/helper.php file a bit:
in getPollOptions function set
$query = 'SELECT p.id, p.text' . ' FROM #__poll_data as p' . ' WHERE p.pollid = ' . (int) $id . ' AND p.text <> ""' . ' ORDER BY p.id';
Joomfish rules !
You have to use table alias with your queries!
I hope it will be fixed on next version!
