The Kandeshop Broken Links Checker is a WordPress plugin designed to identify and list broken or non-functional external links. It scans through your site in batches and organizes links into five tabs:
<ol>
<li>Broken/Unreachable Links: Shows all links (internal and external) that return an error (404, 500) or are unreachable (timeout).</li>
<li>Working External Links: Shows all links that are NOT on your own domain and return a successful status.</li>
<li>Pages Checked: Lists all posts and pages that have been scanned in your current session.</li>
<li>Guide & Limitations: A simple “how-to” guide with important warnings about how the plugin works.</li>
<li>Status Code Explanations: A full explanation of what each error (404, 403, 999, cURL 28) actually means.</li>
</ol>
The plugin now intelligently categorizes errors and features a real-time progress indicator that shows you exactly which post is being scanned.
