[PHP-DB] Header problem

[Dave Carrera]

Hi All
 
My isp decided to upgrade to 4.2.1 without letting us know?
 
So recoded scripts with new $_VARS in place but one thing refuses to
work
 
I have in my script a call to header location.
 
header( "Location: ./file.php");
 
Works on my system but not on theirs
 
I have 4.21 also.
 
Is there anything new with header location that I haven't heard of?
 
Any help is most appreciated.
