no valid crossdomain policy available

Hi, I already checked other forum like this one but the solution don’t work for me (or I don’t understand it well), I making a game where the highscore is send to a php page with this code :

var www = new WWW("http://mywebsite.com/addscore.php?pseudo="+pseudo+"&score="+score+"&asecretekey="+mykey);
yield www;

print(www.text);

it worked well but it stopped to work when I compiled my game and now I got this error :

SecurityException: No valid crossdomain policy available to allow access
UnityEngine.WWW.get_text () (at C:/buildslave/unity/build/artifacts/EditorGenerated/Utils.cs:172)
Login+$Login$10+$.MoveNext () (at Assets/Scripts/Javascript/Login.js:68)

and yes I already try to replace var www = new WWW("http:// by var www = new WWW("https://

Thanx for your help.

I found the solution here, you have to go to EDIT → Projet settings → Editor → adn replace the link in WWW Security Emulation by the link of your crossdomain text file.
