XML Parsing Error: XML or text declaration not at start of entity

Hi there,

I’ve started getting the following error when clicking on my rss feed:

XML Parsing Error: XML or text declaration not at start of entity
Location: https://feeds.feedburner.com/strettyender
Line Number 2, Column 1:<?xml version=”1.0″ encoding=”UTF-8″?>

The feed link is: https://feeds.feedburner.com/strettyender

My url is: https://www.strettyender.com/

I googled the problem and it suggested deactivating my plugins one by one until I found the offending one, but none of them seem to be the problem.

It also suggested deleting blank lines in certain files, but after doing that I got a blank page when I tried to login to wp-admin so had to restore the files.

Any help would be greatly appreciated.

Thanks.
