- Check for URL errors and make sure you're specifying an actual web page file name and extension, not just a directory. Most websites are configured to disallow directory browsing so a 403 Forbidden message when trying to display a folder instead of a specific page is normal and expected.
- Clear your browser's cache. Issues with a cached version of the page you're viewing could be causing 403 Forbidden issues.
- Log in to the website, assuming it's possible and appropriate to do so. A 403 Forbidden message could mean that you need additional access before you can view the page
Tip: If you operate the website in question, and you want to prevent 403 errors in these cases, enable directory browsing in your web server software.
