I love liferea very much which help me read my  love site news.
     But there is some problem puzzle me. I reinstall my linux system (ubuntu), before reinstall it I copy my  whole folder (~/.liferea_1.6) for a backup.  Because I have collected  some sites and updates news . After I install my fresh ubuntu , I copy the whole backup foler(~/.liferea_1.6) to my home folder . And open liferea .But what disappear me is the liferea did't show my collect sites before . So I have to manual  import my collecting feed list . But Istill can't show my downed news. So what I shoud do ?
        Thank you in advance.
