Always got Method DELETE is not allowed by Access-Control-Allow-Methods in preflight response
Try using the CORS extension for chrome, it helped me once.
EDIT
This happens because angular adds X-Header keys in your request headers.
X-Headers generally define or set the operating parameters for the HTTP req/res
You can fix this by modifying the Content-Type of your requests to "text/plain" or "application/x-www-form-urlencoded" or "multipart/form-data".
You can do this by using an interceptor while in your app config.
EDIT
Add this to your server code -
header('Access-Control-Allow-Headers: X-Requested-With');Try changing the content-type to text/plain
Hope this helps.
