[galaxy-dev] Problem accessing test tool shed repositories

Hi, I can't install any tools from the test tool shed into the local Galaxy instances. I can see the list of the repositories but nothing happens when I click on any of them. I can still access repositories in the main tool shed. The same thing happens in fresh installations of both galaxy-central and galaxy-dist. Attached screenshot shows a list of Sequence Analysis repositories in the test tool shed (note the lack of buttons). I'd appreciate any help. Thanks, Ilya
