I am using SEOmoz pro software and my blog tags are bringing up 404 errors.

After checking they do bring back a 404 page, so i am wondering what to do. Do i remove all the blog tags? We use a Drupal cms system.

If your blog tags are bringing up 404 errors, your CMS is not configured correctly. Can you share an example URL of a tag page?

Below is one of the URLs, when clicking on any of the blog tags it takes me to a 404.

Not a hugely experienced SEO'er so any help is much appreciated.

%20 represents a space character.

The proper URL to your "print quotas" tag page is: http://www.altman.co.uk/category/blog-tags/print-quotas

Notice the above link works. You need to examine your site's crawl report, locate the "referrer" field for the 404 error and examine the referring page for the broken link.
