AndyB submitted a new resource:

Link Check - Verifies links in posts are valid and report any which return error code 404.


The Link Check add-on will verify links in posts are valid and report any which return error code 404.

(Example of results page)

(Example of Options page)

URL switches:

Limit: This required switch will determine how many posts will be checked. Note that only posts with the URL tags will be selected. So if you set the limit switch to 50, the first 50 posts with links will be verified....

Likely this will expose thousands of dead links. Please add a function to have dead link reports show up in the report center, so that the appropriate moderator can take care of it.

Thanks @AndyB!
I started to use it. The problem is that I have a forum with 548k messages and lots of broken links, a huge task to check all threads and "unlink" (removes the link but leaves the link text intact) manually:

1º Detect broken link
2º Add a option to unlink:
2.1 Using something like "Post content replacement tool", look for and delete everything OR leave just ""
2.2 That combined with a mass select feature like "user moderation - mass select", so it would be easier to select several broken links simultaneously.

Is it possible to add this feature?

That would make yours a really useful addon!
Thanks for sharing your work :)

As it stands it is depressingly awkward to use and lacks three things that are important.

1. I'd like to see a 'next x' link where x = limit.

2. The mod currently works backwards, starting at the most recent content. It would be useful to have a switch to work forward so we can start at post 1 - Think this is needed because it is older content that is far more likely to have missing links.

3. Please detect and trap bad urls to prevent errors like this:-
Server Error
curl_init() [function.curl-init]: Invalid URL 'http://javascript:AL_get(this, 'jour', 'Pract Mais.');'

I get the following error, when it's set to 404 only. The page loads if I use all errors.:

If more than 50 posts are checked, my page is displaying a generic "504 Gateway Time-out". How do i fix this?


Well-known member
I suggest you install the add-on again. Sometimes files are not copied correctly for whatever reason and this is the error you get when that happens.

Thanks for this addon!

It would be great if you would add a link to the link checker somewhere (For example into the account popup). Or did I just miss a link?
