Expected behaviour:

In the "Top Blocked Domains" box on the homepage an entry for queries to the empty domain (string "") should somehow be clickable and take me to /admin/queries.php?domain=

Actual behaviour:

The entry for the empty domain shows up in the list, but as there is no text in the field it's actually not clickable. If I inspect the DOM I see a <a href="queries.php?domain="></a> is added, but with no text there it's not clickable.

Steps to reproduce:

Reproducible anytime queries to the empty domain shows up in the Top Blocked Domains widget.

I'm not entirely sure how an empty domain is even queried or added to the query log.. @DL6ER, any thoughts?

[dschaper]

Might not be "empty" but just the . root.

Yes, if I run a nslookup . I get an empty domain entry in my query log

Some work has been put into a feature request improving the link dashboard -> stats. This might be the right place to bring this issue up:

I've actually got a quick fix for this, which I need to code up and do a PR for, may not make it into v5, but if not it will follow shortly after in v5.1

This is fixed in version 5.0
