Looking for help on phpbb error

Hey i'm getting a weird error on my site but when i click on the "forum" button and then go to other pages it goes away?

Hi crooklyn

Have you modified the index page at all recently?

 

It has to have been modified.
Up to line 16 is all comments and whitespace out of the box.

Paste in reply everything from the top of index.php to the line which reads:

$user->session_begin();

PHP:

 

i think u need to save the file with UTF-8 without BOM.. this can work..hope so.. because these error are due to improper file formats..

 

thanks all for the responses.
Skinny Vinny was right
