I've just been playing about with a few things and have come across a strange problem. I'm reusing my standard login and user verification code but its saying headers already sent when redirecting. The line that is supposedly causing the headers to be sent is this:

Which strikes me as odd. It seems even stranger that the files are identical to the ones I always use and always work, the only difference is the paths to my includes and the database. Anyone got any ideas? At the moment I'm getting around it by using output buffering, which I don't really like using, I'd rather figure out what the problem is as opposed to just getting round it.

What header code do you have in your script Si, can you post it?

Thats the thing Joe, there isn't any, thats practically the first bit of the file apart from instantiating the class (which also starts the session). There is nothing else, its bizarre. There is a header redirect (header(location: url)) later on but thats the one thats being prevented from working. There is nothing else, thats the line that triggers everything else off like the other session checks or processes the login information if theres no session, its weird as hell. And PHP is throwing a warning over that specific line.
