Need help with Feedburner feed code error

HI everyone,

I recently got my hosting company to help me resolve some technical problems on my blog & I had to re-load all my WordPress plugins into my blog. This included the Feedburner Feedmsith plugin.

However whe i clicked on the “Subscribe to my RSS Feed” on my blog i got the following feed error :

“Internet Explorer cannot display this feed

This feed contains code errors.

More information

Invalid xml declaration.
Line: 2 Character: 3

<?xml version=”1.0″ encoding=”UTF-8″?>”

Can someone explain to me what does this error mean & how to i resolve this so that my RSS Feedburner feeds are working again ?

John
