Bug XML – Fix RSS Feed

Hi !

I got a problem with Lupercalia’s theme.
My RSS feed doesn’t works anymore.

I’ve this error message, when I try to view my feed on https://www.dressmegeekly.com/?feed=rss2

This page contains the following errors:
error on line 2 at column 6: XML declaration allowed only at the start of the document
Below is a rendering of the page up to the first error.

When I try on feedburner, I’ve this other error :

The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 2: The processing instruction target matching “[xX][mM][lL]” is not allowed.

How fix this problem ?

Thanks a lot for any help !
