So I noticed something wrong today…my feed. It was returning an error, and not displaying correctly.

Since I don’t subscribe to to own feed (I’m not that vain), I didn’t see that it wasn’t displaying. It essentially was blank with an error.

Checking out FeedValidator.Org, I saw that it not only wasn’t validating, it had errors on lines 1 and 2…which were empty. Empty I said? Good thing FeedValidator is so smart, it knew what I was using (WordPress) to produce the feed then offered some suggestions to fixing it.

I guess it’s a known problem with some plugins and theme files having empty lines after or before their relative opening <?php or closing ?> tags.

So began the journey to find out what was causing this…

Per FeedValidator’s recommendation, I checked wp-rss2.php and wp-atom.php both of which were fine. Then checked wp-config to see if the problem was there…still no love. I checked my theme’s functions.php file since I use that immensely in customizing the look of this blog but it too didn’t have any empty lines. Next step…checking all the plugins.

For some reason, I started alphabetically from the bottom and checked WP-Super-Cache. Boom. There’s the culprit. Right at the end of the file there was a ?> followed by two empty lines. I deleted those, and all-of-the-sudden the feed validated again. W00t.

Now you 30 people or so that subscribe to my feed…it’s working again. Thanks for hanging in there.
