Why some websites won't load
Why is the page blank?

Many websites block iframe embedding via HTTP headers. This is a security feature protecting against clickjacking.

⚠ How blocking works

Websites send headers telling your browser: "Don't embed me." The browser obeys → blank iframe.

Set frame-ancestors to allow only walkurls.com.

Apache (.htaccess)
Header set Content-Security-Policy "frame-ancestors 'self' https://walkurls.com"
Header unset X-Frame-Options
Nginx
add_header Content-Security-Policy "frame-ancestors 'self' https://walkurls.com";
Node.js / Express
app.use((req, res, next) => {
  res.setHeader('Content-Security-Policy',
    "frame-ancestors 'self' https://walkurls.com");
  res.removeHeader('X-Frame-Options');
  next();
});
PHP
header("Content-Security-Policy: frame-ancestors 'self' https://walkurls.com");
header_remove("X-Frame-Options");
Vercel (vercel.json)
{
  "headers": [{
    "source": "/(.*)",
    "headers": [{
      "key": "Content-Security-Policy",
      "value": "frame-ancestors 'self' https://walkurls.com"
    }]
  }]
}

  Content-Security-Policy: frame-ancestors 'self' https://walkurls.com
Testing

Open DevTools F12 → Console. If blocked:

Refused to display 'https://...' in a frame
because it set 'X-Frame-Options' to 'deny'.

Check headers via terminal:

curl -I https://your-site.com | grep -i "frame\|content-security"

⚠ Never use frame-ancestors * in production

Always specify: https://walkurls.com
