Remote Action on VF page published on SITE does not work

Question

I created a VF page published on Site (http://trapptosemplify-developer-edition.eu2.force.com/TR/Login)

On the page there is a button "Accedi" which trigger a script using RemoteAction for the LOGIN (Code on bottom).

The same code inside SFDC work correctly, but the on site doesn't work. I does not understand why this happen. I published all pages on Site and setted the visibility for all profiles, the same for the controller...

anyone can help me? THNK K.

JSCRIPT:

<script type="text/javascript">
 j$ = jQuery.noConflict();

 function loginUser() {
    var name = j$('#name').val();
    var password =j$('#password').val();        
    var namespace = 'TRRemoteActions.loginAccount';
    alert("ok");
    Visualforce.remoting.Manager.invokeAction(namespace, name, password, function(result, event){
                if (event.status) {
                    window.location = result; 
                } else {
                    j$('#error').show();  
                    j$('#error').html(event.message);
                }               
            }, 
            {escape: true}
        ); 
     }
</script>

APEX

@RemoteAction
global static pagereference loginAccount(String userName, String userpassword) {
    String UserId=null;
    List<Account> loginAccount = new List<Account>();
    try{
        loginAccount =[Select Id, password__c, email__c From Account Where email__c=: userName ];
    } catch (Exception e) { 
          throw  new RemoteVFException('qualcosa di innateso è successo');
    }

    if(loginAccount.size()==1){
        userId=loginAccount.get(0).id;
    } else if(loginAccount.size()==0) {
        throw  new RemoteVFException('nome o password non corretti');
    } else{
        throw  new RemoteVFException('qualcosa di innateso è successo');
    }
    return new PageReference('/TR/InsertTr?uid=' + UserId); 
}

Your issue is because jQuery is not accessible to your Site user and all of the script in the page requires jQuery.

The error shown in the browser is:

Error: ReferenceError: jQuery is not defined Source File: http://trapptosemplify-developer-edition.eu2.force.com/TR/Login Line: 13

To resolve it, change the Cache Control setting on the Static Resource named MobileSample_Resources_jQueryMobile to Public. This will allow the Static Resource to be publicly visible.
