Review redirects and find their source pages — A completed scan of benjaminolsen.dev with the Issues and redirects filter selected. Each row shows the original URL, HTTP result, redirect destination and the pages where the link was found. These 302 redirects lead to the download gateway; a redirect is something to review, not automatically a broken link.

Benjamin Olsen plugin hub with all three active plugins — This website has all three plugins active. Your hub shows the plugins active on your own WordPress site. It stays available while at least one is active.

Find the source, then fix the link

The plugin reads links stored in published WordPress posts and pages, plus shared Oxygen layouts. It checks unique same-site URLs one at a time and reports broken destinations, redirects, restricted responses and request errors.

Each result includes the source documents, so you can open the right editor. The plugin never edits links automatically.

Install and run your first scan

Download the ZIP. In WordPress, go to Plugins → Add New → Upload Plugin, select the file and activate it. From version 1.3.0, future releases appear under Plugins with an Update now link. Already using version 1.2.0 or earlier? Upload the latest ZIP once and choose Replace current with uploaded. Keep at least one Benjamin Olsen plugin active for update checks.
Open Benjamin Olsen → Internal Link Checker with an administrator account.
Select Start new scan. Pause and resume when needed; reports are kept for your account for 24 hours.
Filter issues or redirects. Open a source document, correct its link in WordPress or the Oxygen interface, then run a fresh scan.
Export CSV to share the findings with the person maintaining the site.

Example: a renamed service page

You move a service page to a new URL, but an Oxygen button still points to the old one. The checker reports a 404 or a redirect and lists the layout containing the button. Open that layout in Oxygen, select the button and update its destination through the link control.

Scope and requirements

Requires WordPress 6.0+ and PHP 8.0+. It checks up to 500 published documents and 1,000 unique internal URLs. Up to 20 source documents are listed per URL.

It checks stored links, not a rendered crawl of every page. External links, fragment targets, dynamic shortcodes and JavaScript-generated links are excluded. A 403 or timeout needs investigation and is not automatically proof of a broken destination.

Redirects are followed only within the same site, with a five-request limit. Requests use a five-second timeout. There is no subscription or third-party scanning service.
