Will I continue to have issues or have we addressed the trigger?
Jason,
I did not try your fix before because of your note below:

any place on the site that uses the following code as a trigger:
if(($_SERVER["REQUEST_METHOD"] == "POST") && (isset($_SERVER["HTTP_REFERER"]) && strpos(urldecode($_SERVER["HTTP_REFERER"]), urldecode($_SERVER["SERVER_NAME"].$_SERVER["PHP_SELF"])) > 0) && isset($_POST)){
will fail because of this. on the login page, change that line of code to use the submit button pressed as the trigegr:
if (isset($_POST["LogIn"])) {
you are going to run into this issue on almost every page unless you talk to the host to have them enable the $_SERVER["HTTP_REFERER"] variable

Your suggestions are working. Will I have other issues based on your note or have we changed everything that we needed to?
