Interating script into site design help

nealec · January 27, 2011

Im trying to get a login/register script to work in my existing page design but im getting an error, i have no idea what im doing i know next to nothing about php, i just follow tutorials. Most of the error is hidden because the font is the same color as the background but is says:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/aretheyh/public_html/nealeweb.com/index.php:16) in /home/aretheyh/public_html/nealeweb.com/index.php on line 25

Heres the page link where the error occurs:

http://www.nealeweb.com/index.php

Please help, im useless!

I have gone through it loads of times myself to see if i made any obvious mistakes but none of it makes any sense to me to be honest.

You cannot have any output before anything that needs to send headers.

Sorry to be stupid but i dont know what that means or what to do about it

Didn't test or proof-read; however, compare your original to this...

(MAYBE even print both on paper and compare side-by-side to see differences)

There's a sticky topic on this as well: HEADER ERRORS - READ HERE BEFORE POSTING THEM

Ok thanks thats got rid of the error msg but for some reason the login and register buttons are no longer taking me to the right pages

Try it: http://www.nealeweb.com/index.php

That's because (like I said about me not proofing - GRIN), you probably cut and pasted my code; AND LIKE ME did not see that I forgot the 'p' in the extensions ie .hp should be .php
