RSS Feeds on

  • Author
  • #1936619

    We have a custom RSS reader that is used to gather feeds from members who submit their sites for listing on a page of our own.
    It is written on classic ASP/VBScript and uses MSXML2.ServerXMLHTTP.6.0, and has been working fine up until today apparently.
    Today, it has been unable to get any feeds from blogs on It returns the following error:

    “msxml6.dll error ‘80072f78’
    The server returned an invalid or unrecognized response”

    It works for any WordPress site not hosted on For example, I can check our own WordPress site, which is updated to the latest version (or so it reports). I can also go to the RSS URLs directly, and they open fine in my browser. Our RSS reader has no problems with any Blogspot sites.

    So, I’m wondering:
    Is it a temporary access problem? (Tomorrow will tell perhaps.)
    Have there been updates to that might affect the RSS feeds?
    Would our site somehow be blocked from checking the feeds? (I’ve checked at least 5 or 6, so it’s not like 1 user blocking us.)


    I’ve now taken the XML from one of the problematic feeds, created a classic ASP page, set Response.ContentType to text/xml, and pasted the XML in as the rest of the file. If I check that page using my reader, it reads it sans problem.

    So, there’s no actual problem with the XML itself.
    There’s no actual problem with outputting the XML, because I can go to it directly.
    What else could be an issue during the delivery process, or in outputting the XML, that might make ServerXMLHTTP not recognize it?

    This blog linked to your username is devoid of any blogger created content. We provide support only for free hosted WordPress.COM blogs and it appears that you are posting to the wrong support forum, because you failed to provide any WordPress.COM blog Feed URL. and are completely separate, have different log-ins and run different versions of themes with same names. If you don’t have a username account at WordPress.ORG click and register one on the top right hand corner of the page that opens, so you can post to the support forums there and receive advice from WordPress.ORG bloggers.

    Here’s one I’m trying to check:
    And another:

    I’ve also tried the Atom versions of those,

    I’m posting to the forums, since it is .com sites that are suddenly having the issue. I figured the .org segment wouldn’t have much to say on the matter, especially since all the sites that seem to be running WordPress independently installed aren’t evidencing issues.


    Ah, well, speaking of our own .com account, we do have this:

    And it returns a valid feed when visited in the browser, but not when requested in our reader.

    Oops! I clicked too soon. I meant to tell you that’s a valid RSS feed. I’m sorry but we don’;t provide support for your reader.



    We are seeing this error as well.

    This problem is related to that all servers are sending incorrect headers. You need to inform your developers immediately about this problem.

    This is a problem that is easy for your developers to reproduce by using the following VB/ASP code:

    Set http = Server.CreateObject(“Msxml2.ServerXMLHTTP.6.0”)
    http.Open “GET”, “”, False

    The error message will be:

    msxml6.dll error ‘80072f78’:
    The server returned an invalid or unrecognized response




    Yup, adding ServerXMLHTTP.setRequestHeader did it. Learn something new every day. I guess WordPress just wants to know who’s asking.

    Thank you all for your help.



    Flabberghasted that this error still persists. All feeds on are affected! Thankfully the wider community was able to help where WordPress seem to have refused.

    Hi there!

    I’ve checked in with our developers about this to confirm. But, basically every other modern feed reader handles our feeds just fine. You should validate the feeds you’re testing. If they’re valid, then it’s a problem with your software.

    All of our feeds here at are validating perfectly fine.

    If one of the feeds you’re looking at is not validating, let me know and I can take a look at it.
