Send the site administrator an email when someone encounters a 404 error on your blog

If you create a custom taxonomy in WordPress, whether it’s part of a theme or a plugin, you may encounter a 404 error when trying to view the taxonomy on the front end of your website.
This normally only happens if you are referencing the taxonomy in your permalinks, i.e. if your permalinks look something like this:
/%category%/%postname%/
At first glance this seems to be fine, until you try to navigate to page 2 of the taxonomy archive. This will result in WordPress sending you to a URL something like this:
www.your_site.com/your_taxonomy/page/2
The ‘/page/2’ bit stuck on the end will clash with your permalink settings, causing in an a 404 error.
This plugin fixes that 🙂
