Qual seria a solução?

Olá,

Qual a versão do OpenCart que você está utilizando?
Esse erro acontece logo que você instala a loja, ou depois de mudanças nas configurações ou instalação de extensões?

1.5.5.6 este erro aparece depois.

Segue o código do captcha;

<?php
class Captcha {
protected $code;
protected $width = 35;
protected $height = 150;

function __construct() {
$this->code = substr(sha1(mt_rand()), 17, 6);
}

function getCode(){
//return $this->code;
$out = ob_get_contents();
$out = str_replace(array("\n", "\r", "\t", " "), "", $input);
ob_end_clean();

return $out;
}

function showImage() {
$image = imagecreatetruecolor($this->height, $this->width);

$width = imagesx($image);
$height = imagesy($image);

$black = imagecolorallocate($image, 0, 0, 0);
$white = imagecolorallocate($image, 255, 255, 255);
$red = imagecolorallocatealpha($image, 255, 0, 0, 75);
$green = imagecolorallocatealpha($image, 0, 255, 0, 75);
$blue = imagecolorallocatealpha($image, 0, 0, 255, 75);

imagefilledrectangle($image, 0, 0, $width, $height, $white);

imagefilledellipse($image, ceil(rand(5, 145)), ceil(rand(0, 35)), 30, 30, $red);
imagefilledellipse($image, ceil(rand(5, 145)), ceil(rand(0, 35)), 30, 30, $green);
imagefilledellipse($image, ceil(rand(5, 145)), ceil(rand(0, 35)), 30, 30, $blue);

imagefilledrectangle($image, 0, 0, $width, 0, $black);
imagefilledrectangle($image, $width - 1, 0, $width - 1, $height - 1, $black);
imagefilledrectangle($image, 0, 0, 0, $height - 1, $black);
imagefilledrectangle($image, 0, $height - 1, $width, $height - 1, $black);

imagestring($image, 10, intval(($width - (strlen($this->code) * 9)) / 2), intval(($height - 15) / 2), $this->code, $black);

header('Content-type: image/jpeg');

imagejpeg($image);

imagedestroy($image);
}
}
?>
