RSS feed stopped working

Hi, I have been using wordpress for awhile now on a free subdomain. I recently am trying to figure out why my RSS feed button just up an stopped working. I am guessing since different versions of wordpress made that obsolete possibly with my theme I currently have?

Here is the error code I am currently getting an no clue what it means.

XML Parsing Error: XML or text declaration not at start of entity
Location: https://www.o900lbgorillao.000space.com/?feed=rss2
Line Number 2, Column 1:<?xml version=”1.0″ encoding=”UTF-8″?>
^

If anyone could help me out I would really appreciate it! Thanks!
