This plugin logs 404 (Page Not Found) errors on your WordPress site. It also logs useful informations like referrer, user address, and error hit count. It is fully compatible with a multisite configuration.
This section describes how to install the plugin and get it working.
- Upload the folder named 404-error-monitor in /wp-content/plugins/.
- Activate the plugin through the ‘Plugins’ menu in WordPress
- Configure settings. If you opted for a network install go to network admin dashboard to configure settings.
- Go to 404 Error monitor page to see error list. For network installation, use 404 Error monitor page from network admin dashboard to see error list for the entire network or use 404 Error monitor page located in the settings menu of an admin dashboard to see website error lists individually.
This plugin gives the best 404 error log that I could find from WordPress plugins. The only concern is that the author has not updated it for 1 year. However, so far I have not seen any issues with it.
The major advantages here are:
1. Concatenates 404s by URL. This means that each 404 link takes up only 1 line and I can clearly see how often it comes up.
2. Excluded paths. Other 404 plugins are dominated by various paths from crawlers that want to compromise my site (eg. to /plugins folder). I do not need to deal with these as 404 errors. With this plugin they do not clutter the picture.
3. It displays actual and redirected 404 errors for pages (I did not test posts). I find a major benefit with this approach because it lets me see all internal and external linking issues on my site without the mask of the redirection patch. I can now fix each one directly without the need to look for them.
It’s a great plugin!
The plugin works perfectly, but it lacks some options (IP, user agent).
The fact that gathers the same 404s in one line is amazing though.
I hate that he adds a different menu in the sidebar, it should go under ‘Tools’ section.
If I were a developer I would mix this one and 404 Error log into one plugin.
