I am migrating to another server with a different php configuration and getting this warning:
session_start(): Cannot send session cache limiter - headers already sent (output started ....
I have a main page where i start session and an iframe (the same page), which has another session_start() statement
1. If I remove the session_start from the iFrame, I am not getting this warning, but my code is not functioning properly, because the iFrame cannot get session variables. What should I do?
2. Why did not I have this warning on the old php?
3. Maybe I should replicate exactly the same php.ini file?
4. What php.ini line could supress such a warning in my old php config?
