Sometimes I think we need an FAQ. This sort of error is definitely in the top 10 for PHP errors among newer programmers. When you are doing anything which makes use of HTTP headers, including writing cookies, session variables, or redirecting the browser with the header() function, you must not output any content to the HTTP body. This is different than the HTML body. The HTTP body output begins when you print or echo the first character. A blank line or space character before your first opening PHP tag can generate this sort of error. In your case, the error message tells you where to look: line 2 of constants.php. Make sure that the opening PHP tag is on the first line, first character position of the file. Make sure no print or echo statements are issued. Make sure that no errors are being generated by this file. Beyond this we can't help you since you provided no code for analysis. James _____ James D.
