Broken Link Checker for WordPress
Notice: This plugin has been transferred to ManageWP. I am no longer working on it. Please direct any feedback to the new developer. See the plugin homepage for more information.
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, missing images, deleted YouTube videos and other problems.
- Periodically checks links in posts, pages, comments, custom fields 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.

Requirements
- WordPress 3.0 or later
- MySQL 4.1 or later
The current version of this plugin is only compatible with WordPress 3.0 and up. If you have an older version of WP, try one of the older releases. Specifically, version 0.8.1 is the last one that’s still compatible with the WP 2.8 branch, and version 0.4.14 is the last one compatible with WP 2.1 – 2.6.x.

We used link checker from some time now but, with the last link checker upgrade we are now getting the following error. Has anyone seen this error and know how to fix it?
Error: The plugin’s database tables are not up to date! (Current version : 0, expected : 4)
This error shows up when the plugin has failed to upgrade its DB tables. You can deactivate/reactivate the plugin to force it to try the DB upgrade again. Also, you could try installing the development version.
Hi, I love the plugin, thanks. When I try to edit the page with the broken link I get this error:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 72 bytes) in /home2/distanc5/public_html/wp-includes/meta.php on line 197
If I deactivate the plugin the error goes away. Any suggestions? Thanks.
Sorry, no idea why that happens. For what it’s worth, I’ll look into reducing the plugin’s memory footprint in the future.
Thanks for the reply.

For some time I receive this message after I try to use the Broken Link Checked:
“Error: The plugin’s database tables are not up to date! (Current version : 0, expected : 4)”
I’ve got the latest update of the plugin and my WP blog works under latest version.
Now all my URLs are in the work queue.
How this can be fixed?
Thanks for the help!
Try installing the development version (make sure you deactivate the plugin before installing this version). Once activated, it should display an installation log that tells you where the database update went wrong.
Done! It works! Thanks! I appreciate it!
