Most probably the editor you use to write the code is placing this special character. I've had some trouble with that. Try saving the file with another editor, or setting up your editor not to use any special characters.
Remove all blank spaces before <? and after ?> from all files that are referenced in your code. Headers already sent comes typically due to blank spaces. Also verify each file for special character, even if editpad has not not given issues, it is possible that you may have copied something from the net and has saved the file with formatting info giving special character somewhere.
include_once"includes/db_connect.php"; include_once"includes/functions.php"; logincheck(); PHP: Do either of these files/functions declare session_start() in them? It's possible they are trying to initialize the session even though your main script does it before them. Also - you have a coding error. I doubt this will fix your error, but you are using include wrong, it should be: include_once("includes/db_connect.php"); include_once("includes/functions.php"); PHP:
Try remove the symbol using hex editor, I've had that problem too when I using ultraedit, but now I'm using notepad++ and never get that problem anymore
