JSONP if you are using crossdomain also post some code or else random suggestions will come — Suave Nti, Jul 09 '12 at 21:52

This means that your subject to the Cross Side restrictions put in place by your browser. Consider using JSONP if you can to try and get around this issue or if you can guarentee your users are using more up to date browsers you could get around it by using headers on your webserver. Have a look at the mozilla document about it.

did you switch both your output format and your ajax object to use JSONP? – John Mitchell Jul 09 '12 at 22:05
ok so thats your JSON AJAX request code, but did you change your server to send out JSONP code rather than JSON code? – John Mitchell Jul 09 '12 at 22:09
how can ı do this? It is a remote server on a host – Mehmet Jul 09 '12 at 22:11
If you don't have access to the remote server then I'm afraid your out of luck, you'd have to ask the remote server provider to support JSONP OR edit the Access-Control-Allow-Origin header to be less restrictive. – John Mitchell Jul 09 '12 at 22:12
is there any way with plesk panel? – Mehmet Jul 09 '12 at 22:14
