i tried resolve couldn't find proper solution. me this, cannot understand cause of error.

this due rules of origins (cors), reason javascript(browser) sees request not residing in same server. , reason that, believe, because /home/u919084925/public_html/mod/basket.php not seen valid url on server, should start http://{hostname}/{path}.
