    Warning: Header may not contain more than a single header, new line detected. in /home/verdienmetuwwebsite.nl/public_html/Goedkoopste/wp-login.php on line 269

    I already checked the wp-login.php for spaces but can’t find any.

    The line 269 is: //Set a cookie now to see if they are supported by the browser.
    setcookie(TEST_COOKIE, ‘WP Cookie check’, 0, COOKIEPATH, COOKIE_DOMAIN);
    if ( SITECOOKIEPATH != COOKIEPATH )
    setcookie(TEST_COOKIE, ‘WP Cookie check’, 0, SITECOOKIEPATH, COOKIE_DOMAIN);

    What causes this error?
