Leipe_Po Posted March 15, 2006 Share Posted March 15, 2006 is there any html before the script you posted?like a header file for example? cause session_start needs to be called before any output of html, for example:[code]<?phpsession_start();?><html><head></head><body>// html stuff here</body></html>[/code] Quote Link to comment https://forums.phpfreaks.com/topic/5024-session_start-cannot-send-session-cookie-error/#findComment-17768 Share on other sites More sharing options...
