I have the exact same issue. None of my incoming feeds load in the dashboard. I can’t find any error logs, either.
I also have the “no feed found” error – and I know these feeds are valid because I used the exact same ones on another wordpress + feedwordpress blog, and they worked just fine. Perhaps it has something to do with odd PHP version? The one that doesn’t work is php 5.1.4.
I also have the same issue – I’ll check out bdprss. It has something to do with my PHP install – It works just great on 2 blogs I installed it, and not at all on another server. The only thing I can figure is that it’s something to do with PHP.
