Edit:
After I go: site.com/mypage/comment-page-1/
And I see old page without my comment!
Settings – Subscribe to Comments – Comment Form – Custom HTML ->
<p><label for=’subscribe-reloaded’><input style=’width:30px’ type=’checkbox’ name=’subscribe-reloaded’ id=’subscribe-reloaded’ value=’replies’ checked=’checked’ /> [checkbox_label]</label></p>
