What does a 403 Forbidden error indicate, and how can it be resolved?

A 403 Forbidden error indicates that the server understands the request but refuses to authorize it. This can occur due to several reasons, such as incorrect file permissions, an IP block, or issues with authentication. To resolve this error, you can:

1. Check the file permissions on the server; ensure they are set correctly (typically 644 for files and 755 for directories).
2. Review the .htaccess file for any misconfigurations or rules that might be blocking access.
3. Ensure that the user has the necessary permissions to access the requested resource.
4. If using a firewall or security plugin, verify that the IP address is not blocked.
