Hashtag error when user not logged-in

Jisko 3.0 rc1 on hosted server.

The standard site config shows a Home and Public Notes menu to visitors who are not logged-in. Playing the happy unregistered visitor, I went to Public Notes and then clicked a hashtag. The stats display for hashtags threw an error, saying that function count_tagsByName() did not exist. The call to this function is in the theme /pages/sidebar.php file around line 266.

I fixed this by removing the ELSE clause in this file, which shows the basic menu for unregistered visitors. Our site now has no menu until a visitor logs-in, thus preventing them from accessing site content until the sign-up. That works fine for us.
