Broken Link Checker for WordPress
Sometimes, links get broken. A page is deleted, a subdirectory forgotten, a site moved to a different domain. Most likely many of your blog posts contain links. It is almost inevitable that over time some of them will lead to a “404 Not Found” error page. Obviously you don’t want your readers to be annoyed by clicking a link that leads nowhere. You can check the links yourself but that might be quite a task if you have a lot of posts. You could use your webserver’s stats but that only works for local links.
So I’ve made a plugin for WordPress that will check your posts (and pages), looking for broken links, and let you know if any are found.

Features
- Detects links that don’t work and missing images.
- Periodically checks links in posts, pages, comments and the blogroll.
- New and modified entries are checked ASAP.
- Notifies you on the Dashboard if any problems are found.
- Lets you edit all instances of a specific link at once.
- Gives you a list of all links ever posted on your site, with the ability to search and filter it.
- Lets you apply custom CSS styles to broken and removed links.
- Highly configurable.
The broken links show up in the Tools -> Broken Links tab along. If any invalid URLs are found a notification will also show up on the Dashboard widget. To save screen real-estate, the widget can be configured to stay closed most of the time and automatically expand when broken links are detected.

Can you elaborate? I’m running Windows on my dev. computer and it works fine.

Try the Recheck button. When you press it, does the status display say “Looking for links…” (or something to that effect), or does it go back to “No links detected” immediately? Also, what’s your PHP version?

Awesome plugin. I don’t know how I did not find this till now. Fixed some broken links on my blog, voted that it works on WordPress 2.8.6 and gave it 5 stars.
@ lowspeed : Sorry for not responding earlier. I haven’t been able to come up with a probable cause for the bug, but here’s something you could try to get additional information : the debug version of the plugin.
If you install Firefox, Firebug and FirePHP, you will be able to see the debug messages this version outputs when processing your posts. To do that, go to the plugin’s settings page, open the Firebug console and click the “Recheck” button. It should display a whole lot of information as it parses (or tries to parse) your posts for links.
I don’t know what specifically you should be looking for, but maybe some error message catches your eye.
Thanks for your help, especially since i’m not expecting any support for this.
I installed the debug version. already had firebug so i installed firephp.
When i do recheck, nothing happens (firephp is enabled)
It should just display the info in the browser portion ?
It should display it in the Firebug console, i.e. the thing that shows up when you click the Firebug icon in the status bar.
I get this error:
Database error: Table ‘wordpress.wp_blc_instances’ doesn’t exist
Maybe this will help better i had to remove all the quotes:
Looking for posts and bookmarks that need parsing…
Found 1 items to analyze.

Executing query: DELETE FROM wp_blc_instances WHERE source_id = 1434 AND (source_type = post OR source_type=custom_field)

No links need to be checked right now.
All done.
Hmm, so the plugin failed to create one of its tables for some reason. What version of MySQL do you have?
For reference, here’s the SQL query that the plugin uses to create the table. You could try running it manually and seeing if/why it fails :
(The table prefix is actually not hardcoded, but that’s not relevant in this case.)
if i try to create the table it gives me this error:
The used table type doesn’t support FULLTEXT indexes
I’m using mysql: 5.1.40
need to force the query to ENGINE=MyiSAM not sure how to do it?
According to this page, you just need to add ENGINE = MYISAM after the last bracket in the CREATE TABLE command.
Super, thank for your help.
Maybe you should consider putting that command in the plugin’s next revision.
Thanks again!
Aye, I’ll probably do that. Cheers.
