Composer Archives - Page Not Found

Permalink
I was logged in as admin and clicked on the Composer Blog page Archives for 2014 and Mar link.

The URL is for the link is:

http://mysite.com/cms/!trash/blog-archives/?year=2014&month=03...

And it works fine. It takes me to a the blog-archives page and shows the two blog entries for that date range.

The problem is that if I log out and try it I get again "Page Not Found". Does the same thing on IE v11 and FireFox v27

What is /!trash/ and where is it? Is it all created on the fly?

Any thoughts on how I can get this working for persons not logged in?

Using c5 v5.6.2.1 and Bootstrap v3.0 theme
