Routing issue save error

Routing issue save error

When I try to save my routing setting, I get this error and the page loads forever:

Uncaught ReferenceError: cp is not defined
    at HTMLBodyElement.onmousedown (VM1232 发送选项:213)
wmsbar.js:1 Uncaught TypeError: Cannot read property 'getAttribute' of undefined

    at XMLHttpRequest.d (js.zohostatic.com/zmail/ac/s4/cpanel/js/aclib.js:3) 
I think that the page that is suppose to use ajax to respond got a response in HTML. I think this is a bug. Could you please fix it?

Thank you.
