Any users who may come into this just a heads up.
I went through the link as per Dani and nothing should up i viewed hidden characters and i still got the error.
When i spoke with another developer he looked at the page via SSH and everytime i added security assist it added a
ï»¿<?php require_once('Connections/file.php'); ?>
took this character out and it works fine now, however i am concerned why i cannot view this in Dreamweaver anyone had this before?
