Render State in the User Interface, I am confusion

Tell us what’s happening:
I dont know what I have been doing wrong, but im very sure that my code is right. I think it may be a bug because I have attempted it on many different servers and all say the same thing. Please help me.

Your code so far

class MyComponent extends React.Component {
  constructor(props) {
    this.state = {
      name: 'freeCodeCamp'
  render() {
    return (
        { /* change code below this line */ }
        { /* change code above this line */ }

Link to the challenge:

Your code is correct, and when I paste it into my own window it passes just fine. What do you mean by “attempted it on many different servers”?

I had used chrome, firefox and safari.

That is very strange. I just tried all three of those and they worked. Perhaps try clearing your browser cache?

I had try that several times too. I think it may be a bug?

A bug with what, though? What’s special about your browsers?

Check your browser console while submitting. Do you see any errors or warnings? Take a look at the network tab and verify it’s sending a request.

It says : Error while parsing the ‘sandbox’ attribute: ‘allow-top-navigation-by-user-activation’ is an invalid sandbox flag.

Are you using any extensions, like an ad blocker?

No, I used to though
