As promised/threatened  my award winning stuffed French toast for two recipe. Actually I was awarded a hug from my Mom, and a big fat kiss from my fiance. Possibly not the awards you were thinking of, but I will cherish them always...

Ok, onto the recipe !!!! ... 

If you have used computers and/or the internet for more than a couple years, you have no doubt noticed that in general, things are just faster these days. I often find myself wondering, just how fast could things be, and at what point is pure speed no longer that beneficial.  Well, I think we are just about to find out.

The sotfware uses sessions, and/or sets cookies. For that to work, there can be no output to the browser prior to the session being started. Any of the involved files that have a blank line or space, before the <? or after ?> will cause this error.

PHP is nice enough to tell you what file caused the error, and even points to where in the file the problem was caused...

output started at .... /include/functions.php:1989

This is due to an extra space or line at the bottom of the file  /include/functions.php  which just happens to have 1988 lines of code

If you have permissions, you could also edit the php.ini to enable output buffering and restart your web server, then PHP wont complain about extraneous spaces & lines when starting sessions.
