Incoming Links disappeared with upgrade to 2.7.1

A month or so back I upgraded to 2.7.1 and have had loads of problems, one of which is that the incoming links pretty much disappeared. I had quite a few, and I was at the top of Google searches. Now I don’t show up at all. I have looked in the Appearance menu, checked the widgets, but the only ones I see are about links I’ve posted to other sites. I’ve searched the forums, but evidently am not using the right search terms, because I;m not getting anywhere. I’m using the Comics Press theme and sure don’t know enough to read or edit code.
