RSS Import problems on Invision in wordpress 2.7

I also am having issues with my feed.

This feed USED to work:

https://wcbeacon.rampagenetwork.com/?feed=podcast

or even

https://webcomicbeacon.com/feed/

XML Parsing Error: XML or text declaration not at start of entity
Location: https://webcomicbeacon.com/feed/
Line Number 3, Column 1:

i think the error start with the new rewrite metod for rss in wordpress 2.7.

I have no idea what to do to fix this… it’s seriously effing with the functionality of my site for my listeners.

MadBox: Your feed is fine. Nothing wrong with it.

fesworks: You have the Blank Line problem. More info here: https://validator.w3.org/feed/docs/error/WPBlankLine.html

I think I found the problem! Something I did before. Slight overlook. Urge to kill fading. Sorry! Thank You!

thx fesworks i know my feed is ok but invision say is not valid this happend after upgrade to 2.7

Actually, technically, I think my problem started before 2.7. I was trying to get my Podpress to work, and I put in a code in the wrong spot, then I moved it… without removing a space somewhere… messing it up.
