That error message comes up when you start emitting HTML before calling 'session_start ()'.

If you at the findmenu.php code that you posted, there is an extra space at the very beginning which may be causing your issue.

If not, can you see if HTML is being emitted anywhere before that ... for example in global.php or anything?

You could use output buffering, but problems like this are typical and in most cases it's not necessary to use output buffering.
