annot modify header information - headers already sent by output

Hi All,
Can you please help me with this website issue.
Its a custom website in PHP with Blog included at the bottom.

WORKS PERFECT : When typed http://wwww(.)domainaname(.)com

But DOESNT WORKS : When typed http://domainname(.)com

or DOESNT WORKS : Even When typed http://www(.)domainname(.)com/index(.)php

Code (markup):

So if you see only when www.domainname.com is typed then only it works well
If www is removed from domain name then I get an error
Also I get an error if I add domainname.com/index.php

ERROR : Warning: Cannot modify header information - headers already sent by (output started at /home/content/d/o/m/domainbuyerz/html/index.php:7) in /home/content/d/o/m/domainbuyerz/html/wp-includes/pluggable.php on line 850

Summary : Error throw when typed domainname.com and Works fine with No error when www is typed meaning www.domainname.com works fine

To see Live Error click here : Error without www & No Error with www

All the code for above files index.php, pluggable.php & wp-blog-header.php is copied at below locations for reading, I have copied the code as follows

index.php is found here : http://snipt.org/Umo
pluggable.php is found here : http://snipt.org/Ump
wp-blog-header.php is found here : http://snipt.org/Ung

Can anybody suggest what is going wrong and Please help me to fix this issue

Thanks a lot in advance

its not a fatal error so u could get rid off by adding <?php error_reporting(0); ?> into header.php

 

Hi Crivion, Tried it but same result

Guys, Awaiting more help, Please help me to fix this issue , Thanks a lot in advance

 

"...Cannot modify header information - headers already sent by..." usually means that some content has already been sent to the browser before the request to send headers.

An example would be if you output some content, the use header redirect within the code.

I'd check wp-includes/pluggable.php on line 850 for any output of content to screen.

 

put ob_start(); at the top. this is not 'best practice' code, but it works in a pinch. what it does if buffer all output, so the headers go first.

either put ob_flush(); after you've finished messing with the headers or just leave it and php will clear the buffer at the end of the document.

 

Can you please check and let me know
