What to do when dislike404.com finds an error

Start with the Errors tab

When you open your scan results, the Errors tab is selected by default if errors were detected. This tab shows all URLs that returned a status code of 400 or higher, as well as connection failures. These are the URLs that need your attention.

Not sure what a specific status code means? Check out our HTTP Status Code Reference → for a full explanation of every code and what to do about it.

Step 1 — Open the URL

Click the link icon next to the URL to open it directly in a new tab. This is the quickest way to check whether the error is real or whether it has already been fixed since the last scan.
You can also click on the URL itself to copy it to your clipboard — useful if you want to search for it in your CMS or codebase.

• If the page loads fine — the error was temporary. It will likely resolve itself on the next scan. If it keeps appearing, investigate further.

• If the page is still broken — proceed to the next step.

Step 2 — Find where the link is used

Click the Details button next to the URL to open the detail view. Here you will see a list of all pages on your website that link to the broken URL, listed under "Linked from X Pages".

This tells you exactly where you need to make a fix — you do not have to search your entire website manually.

Step 3 — Fix the issue

Go to each page listed in the detail view and update or remove the broken link. What to do depends on the type of error:

• 404 Not Found — the page no longer exists. Update the link to the correct URL, set up a redirect, or remove the link entirely.

• 5xx Server Error — something went wrong on the server. See our HTTP Status Code Reference → for a detailed breakdown of each 5xx code and what to do about it.

• Connection failure — the URL could not be reached at all. Check whether the URL is correctly formatted and whether the server is reachable.

For a complete breakdown of every error type and recommended actions, see our HTTP Status Code Reference →.

Step 4 — Re-scan or wait for the next scan

After fixing the issue, you can trigger a manual scan from your dashboard to verify the fix immediately. Alternatively, the error will be re-checked automatically on your next scheduled scan.

When fixing is not an option

Sometimes you cannot fix an error — for example, an external website is permanently gone or consistently blocks the crawler. In that case, the best course of action is to add the URL to your blacklist so it is excluded from future scans and no longer appears in your results.

You can add a URL to your blacklist directly from the scan results without leaving the page. For more details, see our How to use the blacklist → guide.
