Session not working in 1 computer

Whatever it is, the problem is in that one PC ... not your code.

But how do I fix it? It's only codeigniter. I can set cookies fine through regular PHP on that computer.

When dealing with session problems in general, it's good to provide your session configuration, and if you're using database sessions, a copy of your sessions table schema. Also, when you say it doesn't work on one computer, what kind of O/S and browser? "Computer" can mean a lot of things these days.

Like Narf said, if it only doesn't work on one computer, then it's probably the computer, but in the past some people had problems with specific browsers. I think that was a long time ago though, and not sure if that's even a thing anymore.
