Annoying problem sometimes encountered when installing WordPress software and running the installation routine:
"Warning: Cannot modify header information - headers already sent by (output started at…"
Means there is a blank line at the start or end of a php file but this is highly unlikely with a fresh WordPress install. So I think your files were corrupted when uploaded to the server. Try uploading them all again – filezilla always seems to work well.
Bloggers date stamping posts prior to 1970 will encounter an error using WordPress as the script processes dates in Unix format. The solution is found here and works well:

Where the web server hosting the WordPress site is located behind a proxy server, the WordPress admin and user may experience technical problems. Symptoms include:
– very slow loading of the dashboard
– askimet not working
These can be resolved by first setting proxy credentials in wp-includes/class-snoopy.php and then editing the akismet_http_post function in wp-content/plugins/askimet/askimet.php along the lines suggested at:
http://comox.textdrive.com/pipermail/wp-trac/2006-August/003435.html
Where your proxy server requires authentication you will need to provide this in askimet.php using the line:
$http_request .= 'Proxy-Authorization: ' . 'Basic ' . base64_encode _
('username:password')."rn";
remembering to substitute in your actual username and password.
The new akismet_http_post function should therefore be:
function akismet_http_post($request, $host, $path, $port = 80) { _
global $wp_version;
// $http_request = "POST $path HTTP/1.0rn";
// $http_request .= "Host: $hostrn";
$http_request = "POST http://$host$path HTTP/1.0rn";
$http_request .= "Host: http://$hostrn";
$http_request .= "Content-Type: application/x-www-form-urlencoded; _
charset=" . get_option('blog_charset') . "rn";
$http_request .= "Content-Length: " . strlen($request) . "rn";
$http_request .= 'Proxy-Authorization: ' . 'Basic ' . base64_encode_
'username:password')."rn";
$http_request .= "User-Agent: WordPress/$wp_version | Akismet/2.0rn";
$http_request .= "rn";
$http_request .= $request;
$response = '';
// if( false != ( $fs = @fsockopen($host, $port, $errno, $errstr, 10) ) ) {
if( false !== ( $fs = @fsockopen('your_proxy_address', your_proxy_port, _
$errno, $errstr, 10) ) ) {
fwrite($fs, $http_request);
while ( !feof($fs) )
$response .= fgets($fs, 1160); // One TCP-IP packet
fclose($fs);
$response = explode("rnrn", $response, 2);
}
return $response;
}
