My contact unit tag is : wpcf7-f125-t1-o1
Contact form 7 works if i modify this lines (i think wp maintenance mode settings should include a list of POST variables authorized) :
if ( ( !$this->check_role() )
&& !strstr($_SERVER['PHP_SELF'], 'wp-login.php' )
&& !strstr($_SERVER['PHP_SELF'], 'async-upload.php')
&& !strstr($_SERVER['PHP_SELF'], '/plugins/')
&& !$this->check_exclude()
) {
$rolestatus = 'norights';
nocache_headers();
if (($_SERVER["REQUEST_METHOD"]!='POST') or ($_POST["_wpcf7_unit_tag"]!="wpcf7-f125-t1-o1")) {
header("HTTP/1.0 503 Service Unavailable");
header("Retry-After: $backtime");
include('site.php');
exit();
} else return;
}
