Hey Guys, i dragged to a simple problem may be but don't know how to deal with it.

I'm on my way to build a chrome extension. The piece of jquery which i use in chrome extension is like this..

Code:

$.getJSON("http://localhost/CI/index.php/welcome/chromeExtension?jsoncallback=?",
    {format: "json"},function(data){
        for (var i in data)
        {
            //alert(data[i].ThreadID);
            [removed](data[i].ThreadAuthorFirstName + " : " + data[i].ThreadTitle );
        [removed]("<br />");
        }
});

My controller function is..

Code:

function chromeExtension()
{
        
    $this->load->model('home/welcome_page_model');
    $data = $this->welcome_page_model->latestThreadsForChromeExtension();
    echo json_encode($data);
            
}

But, right now i'm having strange warning from chrome consol & that is...

"Resource interpreted as script but transferred with MIME type text/html."

Dose any body have any idea how to deal with such kind of situation in codeigniter...
