I tell how to correct this mistake. It is necessary to restore a backup copy of the table w3t_Posts with a new name, for example w3t_Post
execute a script UPDATE w3t_Posts, w3t_Post SET w3t_Posts.B_Body = w3t_Post.B_Body, w3t_Posts.B_Poll = w3t_Post.B_Poll WHERE w3t_Posts.B_Number = w3t_Post.B_Number AND w3t_Post.B_Poll LIKE '%1%'
and then execute a altertablepoll.php from my attachment preliminary having put it on the you site
