Content Security Policy error with Google AdSense frames
15
I'm getting this error in my browser console when loading Google AdSense ads:
**"Refused to frame 'https://pagead2.googlesyndication.com/' because it violates the following Content Security Policy"**
The error doesn't appear every time, but it happens frequently. How can I fix this CSP violation while still maintaining security?

## Content Security Policy (CSP) Error
The error message indicates that the browser has blocked a request to load a frame from ad sites due to a violation of the Content Security Policy (CSP).
**Causes:**
1. CSP configuration issue
2. Insecure content (HTTP) embedded in HTTPS page
3. Frame-ancestors directive mismatch
4. Google AdSense configuration issue
**CSP Directives:**
1. **frame-ancestors:** specifies allowed frame ancestors
2. **frame-src:** specifies allowed frame sources
3. **child-src:** specifies allowed child sources
**Solution:**
1. Update CSP configuration:
- Add *frame-ancestors* to allow Google AdSense frames.
- Add *frame-src* to allow Google AdSense frames.
2. Ensure HTTPS content:
- Verify that all content, including ads, is served over HTTPS.
3. Verify Google AdSense configuration:
- Check AdSense settings for correct frame-ancestors and frame-src directives.
