[mythtv-users] mythweb error with 0.14

[malcolm-mythtv]

I just upgraded to 0.14 and also upgraded mythweb to 0.14 and now at the top 
of every page I get this:

Warning at /var/www/html/mythtv/includes/init.php, line 46:
session_start(): open(php_sessions/sess_8b8596e33e1a554b7e6eaa97f2fd2e9b, 
O_RDWR) failed: No such file or directory (2)

I looked at line 46 in init.php and it has this:

session_start();

So I checked /etc/php.ini and it defines "session.save_path = /tmp" so why 
can't it write the session file?

Thanks for any help.
BTW - I rebooted after upgrading and it didn't make any difference.

PS. I compiled both from source.
