What are common CORS errors and how can I fix them?

Common CORS errors include 'No 'Access-Control-Allow-Origin' header is present' and 'CORS preflight request failed'. You can fix them by ensuring your server includes the appropriate CORS headers.

What does the 'No 'Access-Control-Allow-Origin' header is present' error mean?

This error means that the server did not include the 'Access-Control-Allow-Origin' header in its response, which is required for cross-origin requests.

How can I enable CORS on my server?

To enable CORS, you need to configure your server to include the 'Access-Control-Allow-Origin' header in its responses. This can usually be done in your server's configuration or code.

Are there any security risks with enabling CORS?

Yes, enabling CORS can expose your server to security risks if not configured properly. It's important to restrict allowed origins to trusted domains.
