Problema conexión web con base datos wordpress

[yukuve]

olvidé poner el código:

function si_contact_start_session() {
// start the PHP session - used by CAPTCHA, the form action logic, and also used by vCita
// this has to be set before any header output

// start cookie session
if( !isset( $_SESSION ) ) { // play nice with other plugins
//set the $_SESSION cookie into HTTPOnly mode for better security
if (version_compare(PHP_VERSION, '5.2.0') >= 0) // supported on PHP version 5.2.0 and higher
@ini_set("session.cookie_httponly", 1);
session_cache_limiter ('private, must-revalidate');
session_start();
}

la línea 1997 es la penúltima: session_start();
