Jquery ajax returning 404 not found

I'm using Ajax to pass my form data and files to a PHP file for processing.

Javascript:

$("form#applyform").submit(function(){

var data = new FormData();
jQuery.each($('#file')[0].files, function(i, file) {
    data.append('file-'+i, file);
});

$.ajax({
    url: 'ValidateApplication.php',
    data: data,
    cache: false,
    contentType: false,
    processData: false,
    type: 'POST',
    success: function(data){
        alert(data);
    }
});

}

ValidateApplication.php definitely exists. I can view it if I type in the address into the web browser, however when I submit the form chrome console returns 404.

The PHP is in the same folder as the HTML page the JavaScript is running on so I am confused as to why I keep getting a 404.

UPDATE

Changing POST to GET gets rid of the 404 error, but returns a 500 Internal Server Error

UPDATE 2

Changing the action of the form to ="ValidateApplication.php" and submitting it as normal (without AJAX) leads to the correct file without any errors.

I had the same problem. Most probably you have renamed the file ValidateApplication.php or forgotten to rename.

Based on my case, I'd be sure to recheck your url address.

Please check your PHP page name!

Do not use page-ajax.php, but instead use page_ajax.php.

For me, it was that I used an input field with name="name" which made the called page return a 404. Weird stuff, hope this helps someone.

It seemed to be a problem with the FormData object. Once I changed my method to use .serialize() instead, the page worked just fine.

$("form#applyform").submit(function(){

    var data = $("form#applyform").serialize();
    jQuery.each($('#file')[0].files, function(i, file) {
        data.append('file-'+i, file);
    });

    $.ajax({
        url: 'ValidateApplication.php',
        data: data,
        cache: false,
        contentType: false,
        processData: false,
        type: 'POST',
        success: function(data){
            alert(data);
        }
    });
}

I've had the same issue and after 2 hours looking for what was causing the 404 Not Found error I found that I was recently playing with the header() from PHP and had forgotten to delete the following line of code: 

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");

After deleting it, my Ajax functions became normal again.

Try adding a / before the filename: url: '/ValidateApplication.php',

Try changing the request type from POST to GET and see if it works.

Try commenting out parts of the code:

/*cache: false,
contentType: false,
processData: false,*/

Try another browser.
