I have a VPS. If I set the php version to 5.3 or 5.4 for the domain, I can't set cookies. It gives an error:
Warning: Cannot modify header information - headers already sent by (output started at /home/.../test.php:1) in /home/.../test.php on line 2
Here is the code. There is definitely no whitespace before the opening bracket.
This works fine in php 5.2.
How do I get it to work in 5.3 and 5.4?
