A 403 error can be a frustrating interruption to anyone’s day; it can lead to exasperated website visitors, even leading to lost traffic and website revenue depending on the affected page. When you (or your site visitors) encounter an unexpected 403, it’s vital to assess the issue promptly in the event that it’s the symptom of a more serious issue on your site.
You might run into a 403 forbidden error when visiting a website directory or page with restricted permissions, as most websites are set up to disallow directory browsing to protect sensitive files.
