feed url not working

Hi Hb-Themes,
I have a small issue with my feed. Everytime i visit my feed; i get this error;
XML Parsing Error: XML or text declaration not at start of entity
Location:
Line Number 2, Column 1:<?xml version=”1.0″ encoding=”UTF-8″?>
^

I check online for a fix and many suggested their could be a white space. I try different methods but i was unable to make it work. If you dont mind; can you check this issue for me.

Thanks
Manzoor
