As mentioned before (http://www.woopra.com/forums/topic/wordpress-plugin-woo_widget-bug-causes-not-collecting-any-data) line 182 (was line 181 before plugin-upgrade) is buggy:
update_option('woopra_website_id', (int) $_POST['websiteid']);
forces an int-cast. When you edit the options on the options-page website-id's bigger than 2147483647 are going to be stored as 2147483647 in the db. That line should read something like that:
update_option('woopra_website_id', $_POST['websiteid']);
