Show welcome page only to users that are not logged on

Bit of a hack but – Within the index template before anything else happens you could do something like

<?php
if (!$user_ID)
{ header(‘Location: https://www.example.com/welcome&#8217;);
exit;}
?>

It looks like you are on the right track, but it doesn’t work right. When I go to https://www.example.com it redirects to https://www.example.com/welcome, but I get the following message in Firefox.

The page isn’t redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

To clarify what I did: I copied your code to the very top of index.php on the root of my website and changed the URL from example.com to my own URL.

Let me know if I am doing something wrong.

Never mind I fixed it.

For those of you who want to know, the code is supposed to go in the theme index.php file, not the root index.php file.
