After updating the blog to the iFeature Pro 5 theme, comments are not being displayed. The contents is there, but something in the template code prevent them from being displayed. I have contacted their support, and hope to have it working soon.
There are also a couple of other issues that I (as well as other users) experienced and reported, and the makers of the theme are in the process of fixing it. That is why the slider at the top of the main page is gone. The major issue is however that images are not being inserted. They have to be coded by hand using HTML, after being uploaded to the blog. A fix is promised for the next version, due out in a few days.
