RSS feeds not showing any thing

Hi,

My feeds stopped working and I am not sure what happened.

Feed URl: https://feeds.feedburner.com/TechSnafuFeed

Here is the message I get when I try to validate:

This feed does not validate.

line 1, column 0: XML parsing error: <unknown>:1:0: no element found

In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendation.

Feeds should not be served with the “text/html” media type

I am using feedburner and “redirection” plug-in to redirect RSS to feedburner. It worked in the past, but after few weeks that I checked the RSS, it was blank.

Thanks
