    RSS Error: A feed could not be found at A feed with an invalid mime type may fall victim to this error, or SimplePie was unable to auto-discover it.. Use force_feed() if you are certain this URL is a real feed.

    Obviously this is a known issue and has been cited in the forums many times. Is there a fix for my particular site or anything that can be updated to help the issue?

    I’m trying to post my podcasts to iTunes but I need an operable feed first.

    Unfortunately that link you provided redirects over to a Feedburner error page so there’s no way to verify whether your feed is working or not. You’d have to disable the Feedburner plugin you’re using to see what happens when you go to the feed link without Feedburner installed.

    If it’s genuinely a 404 error you might want to take a look at the plugins you have installed into the site. I think some SEO plugins have an option to disable the feed links in the site (which would obviously cause a problem if you need the feed links).

    It’s also possible that it’s a problem with the theme in your site. Do you know for sure that your theme’s header.php file has a wp_head() call in it? Without a wp_head() in the header.php (inside the <head> section of HTML) your site could definitely have problems too. That said, a missing wp_head() call “shouldn’t” actually eliminate the feed from your site – just cause problems finding the feed.

    The wp_head() call would look something like this:

    <?php wp_head(); ?>

    It would simplify things if you weren’t forwarding your feed to feedburner. Why don’t you stop doing that?

    I did stop the forward. It must have been just after your guys’ replies.

    Anyone feel like trying again?

    The header is in the header.php editor.

    It’s still forwarding.

    Really? Can you tell me how to take out the function that forwards the feed?

    Scott Fennell


    So, wait, how are you confused about this?

    When you go to

    are you forwarded to ?

    If so, your feed is being forwarded, most likely by a plugin. Remove your plugins one by one to figure out which one is doing it.

    I’m confused because I have done that. There are no more plug-ins to delete.

    Hmmm… Try switching to a bundled theme such as twentythirteen.

    I tried switching between several themes. I suspect that deleting and reinstalling the entire site would fail as well because it is something to do with the URL? Or is that incorrect?

    Scott Fennell


    If it’s not a theme (which, if you run a fresh version of twentythirteen, it’s not ( although you currently are not running twentythirteen ) ) and if it’s not a plugin (which, if you have no plugins, it’s not) and if it’s not core (which, if you are running an un-hacked version of core, it’s not), then that really narrows down the possibilities.

    How about htaccess? Have you edited htaccess at all? Make sure there are no redirs in there.

    What did you do to redirect your feed to feedburner in the first place? You did something to make this happen. It’s not a “known issue”.
