500 Internal Server Error On XHR Request

Here is my code: var fd = new FormData(document.querySelector('#form-step1')); var xhr = new XMLHttpRequest(); xhr.open('POST', '/Handlers/newAccount_handler.php', true); xhr.sen

Solution 1:

There is nothing wrong with the last line. The '500 Internal Server Error' is simply the result the server sends back as the result of the request.

This means that '/Handlers/newAccount_handler.php' is the real problem. If you open this URL in a browser it will show you an error.

Solution 2:

This seems a bit old, but I've had similar issue. It's worth checking what the value of '#form-step1' you are sending. In my case if the value contained quotes it would throw an error, but with simple text it worked fine.
