title: Strange Facebook Debugger errors with Blogger links: redirects to “.pe”, says “article:author” unsupported by “og:type” “article”
body: <p>Starting yesterday evening I noticed sharing links to my Blogger blog on Facebook wasn’t working right: images failed to load, the meta description was missing, various other errors. (Sharing links from other sites worked fine, so this seemed to be Blogger-exclusive.) Running the permalink through the Facebook Debugger returned 4–5 errors that hadn’t been there for previous links I’d shared, and some of these errors have since disappeared on their own. I figured FB had messed with their scraping system and that it would be rectified soon.</p>
  
  <p>Presently, link-sharing works better, but a couple issues remain that I can’t explain or find any solution to: 1) Facebook tries to redirect my <code>.com</code> blog to <code>.pe</code>, and 2) it claims the meta property <code>article:author</code> is incompatible with the <code>og:type</code>, which is <code>article</code>.</p>

  </ul>
  
  <p>For the record, I did some minor meta tag editing the day before this problem began, yet I validated the page when I finished and received no errors at the time (except for the missing <code>fb:app_id</code>, which I ignore).</p>
  
  <h1>1) Facebook Debugger redirects to <code>blogspot.­pe</code></h1>
  
  <p>My blog is at <code>preliator2.blogspot.com</code>. Every URL in the site source uses <code>.com</code>. There’s a simple script in the header that redirects any country-specific URLs (blogspot.ca, blogspot.ru, etc.) to <code>.com</code> for reasons of consistency and compatibility.</p>
  
  <p>This has never caused a problem with Facebook sharing. Yet now, the Sharing Debugger gives me this (note the <code>.pe</code> domain):</p>
  
  <pre>
  Fetched URL    https://preliator2.blogspot.com/2017/08/17-Isnt-it-the-thought-that-counts-124.html
  
  Canonical URL  http://preliator2.blogspot.pe/2017/08/17-Isnt-it-the-thought-that-counts-124.html
  
  Redirect Path  Input URL         → https://preliator2.blogspot.com/2017/08/17-Isnt-it-the-thought-that-counts-124.html
                 302 HTTP Redirect → https://preliator2.blogspot.pe/2017/08/17-Isnt-it-the-thought-that-counts-124.html

  </pre>
  
  <p>And this is the link preview:<br/>

  <p>Further, on the Object Debugger page, fetching new scrape information gives me this error:</p>

  <p>For some reason, the Facebook scraped URL shows the canonical and other blog links as <code>blogspot.pe</code>, yet in my blog’s actual source, all links are <code>.com</code>. I have no idea why Facebook sees/adds all those <code>.pe</code> domains. The blog isn’t based in Peru.</p>
  
  <h1>2) Says <code>article:author</code> isn’t supported by <code>og:type</code> (<code>article</code>)</h1>
  
  <p>I also receive the following error from the Sharing Debugger:</p>
  
  <blockquote>
  The following properties are specified on the webpage but NOT supported for the specified 'og:type': article:author
  </blockquote>
  
  <p>Yet here are the relevant tags as they appear in the scraped URL:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;meta content="{FB_profile_URL}" property="article:author"&gt;
  &lt;meta content="article" property="og:type"&gt;
  </code></pre>
  
  <p>Last I checked, <code>article:author</code> is perfectly compatible with <code>og:type</code> <code>article</code>. The meta tags are in the <code>&lt;head&gt;</code> section. I don’t know whether this error is related to the strange <code>.pe</code> redirect issue.</p>
  
  <p>How do I stop that nonsensical redirect and get FB to play nice with author/og:type meta tags?</p>

  <h3>Update:</h3>
  
  <p>Problem’s still occurring. I’ve also done a couple tests, with the following results.</p>
  
  <p><strong>A)</strong> I tried sharing a link from another Blogger-hosted site, specifically the <em>Official Blogger Blog</em> (<a href="https://blogger.googleblog.com/2017/03/share-your-unique-style-with-new.html" rel="nofollow noreferrer">https://blogger.googleblog.com/2017/03/share-your-unique-style-with-new.html</a>). Worked without a hitch. This indicates the problem is specific to my blog.</p>
  
  <p><strong>B)</strong> The problem started only a day ago; link sharing worked just fine before then. So I dug up a backup of my blog template from a week ago and applied it to the blog. I then tried sharing a link again and rescraping. No change – even though link sharing worked without any redirects or other issues with <em>this exact template</em> just days ago. (I’ve since reverted back to the newer template, since evidently it doesn’t change anything.)</p>
  
  <p>I still want to think the problem is on Facebook’s end, but this has been going on for almost two days now. If anyone has any ideas, that’d be greatly appreciated.</p>
