solved. the issue was not where achecker pointed, problem created at icon box element texts which had an element with same id and after cloning remained there and caused the issue
Thanks for the help anyway and the immediate response
thanks for the reply i changed id in body but it did not work. same result Is there a way that jquery – javascript creates this problem i even checked dev tools console and it gives me 1 as length to this body id . Maybe the id that is not unique is not body but achecker cannot give the exact location . can i check somehow for duplicate ids or is there a way throug console
