Hello,

Today i discovered that my dev version of my website do not execute success callback, but all other javascript and jquery code is running good. Even my ajax request is performed and i can see response in firebug.

$('#login').submit(function(){
    var email = $('#l_email').val();
    var pass = $('#l_pass').val();
    if(email && pass != ''){
        var str = decodeURIComponent($(this).serialize());
        $.ajax({
            type: "POST",
            url: "login.php",
            data: str,
            success: function(msg){
                if(msg == 'OK'){
                    window.location = 'index.php'
                }else if (msg == 'NOT_OK'){
                    if(lang == 'lv'){
                        alert(message);
                    }else if(lang == 'ru'){
                        alert(message);
                    }
                }else if (msg == 'EMAIL_NOT_VALID'){
                    if(lang == 'lv'){
                        alert(message);
                    }else if(lang == 'ru'){
                        alert(message);
                    }      
                }
            }
         });
    }else{
        alert('That form is empty.');
    }
    return false;
});

The thing is $.ajax part executes fine and i can see response in firebug "OK". But redirect is not happening and even if i replace that redirect with something like alert or console.log nothing comes up.

What could cause this? It's really hard to track since firebug gives no errors.
