My Podcast's Feed's is Chucking a 404

[trailofants]

My Wordpress 2.8.5 website is http://www.trailofants.com, and the
podcast feed is http://www.trailofants.com/feed/podcast and my problem
is related to my podcast feed suddenly responding with "Server
returned HTTP Error 404: Not Found" when I try to validate it.

You can see this here; http://www.feedvalidator.org/check.cgi?url=http%3A%2F%2Fwww.trailofan...

The reason I did the Feed Validator in the first instance is because
iTunes was failing to pick up my latest podcast post, and returning
the following error;

"There was a problem downloading "Trail of Ants" The URL "http://
www.trailofants.com/feed/podcast" could not be found on the server.

On further investigation, I've discovered that of the five episodes
I've broadcast, iTunes can see four of them (not the latest one);
Feedburner can see three (not the last two); and Blubrry (http://www.blubrry.com/trailofants/) can see four (not the last one)

Obviously I'd like for me to be able to see all of them, but I can't
figure out why Feed Validator is throwing back the 404.

FeedBurner's PodMedic displays the three that the Feedburner service
can see, and confirms it's all OK.

Perhaps you've had the same problem and can offer some advice? Perhaps
you're an expert in this field? What are your thoughts please? Have I
missed some vital info that you could use to help diagnose?

[I've tried Angelo's suggestions in response to TJFisher's similar issue.]

ps. Thought this might be a clue: The Feedburner Feed has always shown zero subscribers; despite there being at least one (me)

This is most likely due to another plugin conflicting with the linking cache in WordPress. I just coded a fixe in the development version of PowerPress (I'll be releasing this in the next couple of days). If you are comfortable with manually downloading and installing the latest version of PowerPrses via FTP to your web server, here's the link: http://downloads.wordpress.org/plugin/powerpress.zip Let me know if that fixes your 404 problem.

Also, if you don't mind replying with a list of your active plugins, I will test them in my local development environment to figure out what could be causing the conflict.

I already disabled HeadSpace2

I'm hoping it's not WP Super Cache — the last time I disable that it pulled the plug on my whole site and took me a week of headaches to get it back online!

Cheers

It should not be the WP Super Cache plugin, but keep in mind if you installed PowerPress after you had the WP Super Cache plugin enabled, then you need to go into the WP Super Cache settings and clear the cache so it rebuilds.

[trailofants]

I cleared WP Super Cache's cache; then validated my podcast feed while disabling each of my active plugins one at a time (with the cache disabled) — still the same result of the 404.

With the development version of PowerPress linked here? http://downloads.wordpress.org/plugin/powerpress.zip

I'm having a similar issue. When I try to verify my mp3 file, I get the "The requested URL returned error: 404" error. This has not happened with my earlier episodes.

[angelo]

Verifying a media URL is a different problem, this thread is about the podcast feed being 404. Please try the following URL and click 'Verify' to see if you still get the 404 error.

Code: [Select]

http://media.blubrry.com/blubrry/content.blubrry.com/blubrry/FlowPlayerClassic.mp3

[epicdeer]

Thanks for that suggestion. That URL works, but mine still doesn't. And I've posted several episodes previously to this one. If I put in any of them to verify, the 404 error comes back.

[angelo]

Can you reply with a URL to one of your media files that is returning 404?

One other note, blank spaces can cause this, make sure you don't have any spaces after the file extension.

[trailofants]

Hi Angelo, yes I did it with that version of the plugin (1.0.3). To be sure, I reinstalled it and redid the test — same 404 result.

[epicdeer]

Angelo,

It's http://theicequeens.com/wp-content/uploads/IQ306a.mp3

As you can see, no spaces.

Thanks for looking into this!

[angelo]

Well I figured out the problem. I just clicked the media link in my browser and I am directed to a 404 page.

The Verify feature works, as it did properly detect that the media file is 404.
