In der "global.php" sollte geändert werden
// Initialize CAPTCHA configuration
$captcha_enable = 1;
$captcha_enable_comments = 1;
$captcha_enable_upload = 1;
$captcha_enable_registration = 1;
$captcha_enable_postcards = 1;
$captcha_ttf = 1;
$captcha_path = ROOT_PATH.'captcha';
$captcha_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
$captcha_length = 5;
$captcha_wordfile = 0;
$captcha_width = 200;
$captcha_height = 70;
$captcha_text_color = '#000000';
$captcha_text_size = 25;
$captcha_text_transparency = 60;
$captcha_filter_text = 1;
$captcha_filter_bg = 1;
NEU:
// Initialize CAPTCHA configuration
$captcha_enable = 0;
$captcha_enable_comments = 0;
$captcha_enable_upload = 0;
$captcha_enable_registration = 0;
$captcha_enable_postcards = 0;
$captcha_ttf = 0;
$captcha_path = ROOT_PATH.'captcha';
$captcha_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
$captcha_length = 5;
$captcha_wordfile = 0;
$captcha_width = 200;
$captcha_height = 70;
$captcha_text_color = '#000000';
$captcha_text_size = 25;
$captcha_text_transparency = 60;
$captcha_filter_text = 1;
$captcha_filter_bg = 1;
Dann ist der Code komplett abgeschaltet.
ich hoffe, nun auch mal geholfen zu haben
