title: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent
body: <p>I've read a lot on other forums, they said that the error was that there was White-space before the session_start but I'm extremely sure there isn't, my file is encoded in UTF8 without BOM so that white-space problem should be fine and it's working perfectly on local (I'm using easyphp). Still, as soon as I put it online, it pops me those problem.anyone can help? They're telling those two lines of error online :</p>
