I have ran into this before and I belive it was a php.ini problem.
I have a file in EX home/users/cgarlick/comic/index.php
With the line header(‘Location: admin/install.php’);
So it should look in the current directory but it jumps to the root insted.
Insted of looking in http://www.website.com/comic/admin/
its looking in http://www.website.com/
I have tried header(‘Location: ./admin/install.php’);
But it still jumps to the root?? Any ideas?
