Never mind the question before,
I edited the polls and inside it the ID and shortcode was listed.
But I`m having another issue, the polls are working in a strange way, sometimes it work as it should, with the Ajax loading icon and the message of vote succesful, and other times it will just reload the page with this sufix in the address:
?yop_poll_answer=207&yop_poll_tr_id=&yop-poll-nonce-23_yp5329c74555191=3f6d58a1e1
and won`t place the vote nor show any message.
Any clues?
