Do you have session_start(); at the top of your script?

This is what the file looks like...always worked..I tried to add some code in functions.php last night, plus I installed a new plugin which showed me an fatal error message...not sure what caused this message...I thought I had some white spaces to delete but after I tried still not working...maybe the plugin caused the mess...who knows

Hey,
I don't no wordpress ,Its just the logic behind ur error okey...

1. R u using any header function ?
2. If yes check whether you have echoed out anything to the browser before ur header function. In most of the cases header function will break out if u have echoed any thing to the browser before it is called.
