When project is put into some namespace, URL in notification emails (e. g. notification about new issue) doesn't contain namespace and thus points to non-existing page. The same happens with search box - if I search for project that is under some namespace, search box can find it but clicking on it shows me 404.

For example, when issue is opened for project https://pagure.io/fedora-qa/check-compose, notification email contains:

To reply, visit the link below or just reply to this email
https://pagure.io/check-compose/issue/1

If I try to search check-compose using "Search projects" on Browse page, it shows me project check-compose, but clicking on it takes me again to this non-existing page: https://pagure.io/check-compose.
