升级到Php 5.5.30和Apache 2.4 Session错误后

Php 5.4 and Apache 2.2 all my website were working, after upgrading to php 5.5.30 and apache 2.4 I am getting these error message on log file on every domain on the server

[25-Nov-2015 01:55:44 UTC] PHP Warning:  session_start(): Cannot send session cache limiter - headers already sent (output started at /home/mysite/public_html/qa-include/ajax/asktitle.php:76) in /home/mysite/public_html/qa-include/app/users.php on line 146

What should I check on the server or where do I look at?

Session info from phpinfo()

Everything set correctly????

Well my host fixed the problem, Somehow, even session path defined in server php.ini adding this little local php.ini to the domain root with

session.save_path = "/home/mysite/tmp" 

fixed this problem...
