i am running 2.8 and still having same issue. But i am relatively new to this plugin. I got a question for you guys. Did it worked before 2.8 upgrade?? If so, that means something within 2.8 upgrade had caused it to stop working. I am looking into it right now. Not a programmer, but i can take a look at the codes to see if i can tweak it to work again.
This plugin is awesome and gets everything i need in parts of customization. Looks like the guy that design this is no longer supporting it. This is one of the best RSS plugin i have seen so far.
