We have also faced the same issue.
What we did was updated :
$path = $_SERVER[‘HTTP_HOST’] . $_SERVER[REQUEST_URI];
$path = $_SERVER[‘HTTP_HOST’] . $_SERVER[‘REQUEST_URI‘];
i.e. change made : REQUEST_URI to ‘REQUEST_URI’
Let us know in the comment section if it works for you.
P.S : If you are not an experienced person to do it, we would recommend to pass it to your developer or contact your hosting provide to have a better understanding of the issue.
