I have started to try adding this to my site and I have a lot of frustrations on the lack of detail on the issue facebook is facing as the instructions are carefull followed, applied and tested. I even used tools like OpenGraphCheck.com which is able to retrieve the meta tags like shown here. I had even tried testing posting on LinkedIn the url and it works (only 'og:description' not printed). But Facebook is a crazy mess where it does not give you details and no matter how many times you tell it to recheck it will always say these errors. checking viewsource you can see everything is placed as expected. Thanks in advance for those who can assist :)

The Facebook scraper can be a bit fussy, when it gets served faulty HTML.
If you follow the See exactly what our scraper sees for your URL link at the bottom of the debug tool output, it gets displayed like this:
<!DOCTYPE html>
<html><body>
<p>
</p>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
…
Validating your HTML shows this as the first error,
Non-space characters found without seeing a doctype first. Expected <!DOCTYPE html>.
At line 1, column 1
is a ZERO WIDTH NO-BREAK SPACE, see Why is appearing in my HTML?
This can mess up the correct parsing of your document using a DOM parser, and that is likely the reason Facebook does not “see” your OG meta tags here.
So figure out where from this character makes its way into your output, and remove it.
I have an issue with facebook. When i'm looking my site's code in inspect element everything is fine. But facebook reads it wrongly. For example this post: http://aww.ge/ratom-asxams-es-kaci-mwerebis-sawinaaghmdego-spreis-windaze-imitom-rom-geniosia1/
In first 3 lines everything is fine, but fb reads:
<!DOCTYPE html>
<html><body>
<p>
Any solution?
Header.php was saved in BOM.
This was main proble, after I fixed this, everything is OK.
Can someone help solve this problem with meta tags in body?
I have a wordpress site and I'm using the open graph wordpress plugin to make the facebook image default to the featured image. It is not working properly. When I debug it on the opengraph debugger, I get ...
*
*Meta Tags In Body*Your page has meta tags in the body instead of the head. This may be because your HTML was malformed and they fell
lower in the parse tree. Please fix this in order for the tags to be
usable.
*
Can anyone look quickly at the debug link and tell me how to fix it? Here is a sample URL: http://wilmettefeed.com/wh-42/
thanks!
Your HTML, indeed is malformed. On line one of your document the source shows:
<div id="nmlurkoverlay">
<!DOCTYPE html>
<html lang="en-US" xmlns:og="http://ogp.me/ns#">
A function somewhere is outputting code before the wp_header(); function. Could it be your justified-image-grid plugin? Or whatever involves outputting id="nmlurkoverlay". Find and fix this, and you will resolve your Facebook Open Graph Tags issue.
The <div id="nmlurkoverlay"> could come from a function, but could also be hard coded in the header.php file in your active template folder. Check there first.
So, I'm building a website called "dagbok.nu", which is swedish for "diary now" :)
Anyway, when creating the Facebook application, it claims that the site URL is invalid as well as the app domain. For site url, I used "http://dagbok.nu" and for site domain, I used "dagbok.nu". Please don't reply (as I've seen others do on similar issues) that I should type the site url with the scheme and the domain without - that's exactly what I'm doing.
Right, so according to another question here, one could trouble shoot this functionality using FB's own URL scraper, so I did just that:
http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fdagbok.nu
And the reply: Error Parsing URL: Error parsing input URL, no data was scraped
Right, so now I can assume that the reason for it being considered invalid is because of FB not being able to scrape the URL. But why?
According to this question, one of the reasons seems to be that FB has deemed the URL insecure or "spammy". I've acquired this domain from a previous owner so this wasn't all that impossible. But when doing the same thing as Matthew in that post - i.e. trying to post in my timeline using the domain "http://dagbok.nu", I didn't get any information. The status box expanded as if to include a thumbnail and information about the link, but it only contained a "(No title)" text and nothing more.
So now I don't know what to do. I've tried to check the DIG and NS records from multiple servers around the web, and everyone seems to resolve it correctly, and I've had friends double check the URL from the states as well. I can't understand what's wrong and I have no idea how to ask someone at FB how to resolve this. Does anyone here have a good advice for this? Thanks in advance! :)
EDIT
When changing the domain to another domain that points to the exact same web server and document_root, it works! So this is definitely a problem with the domain "dagbok.nu" and not with the code on that page.
EDIT
When using the debug function above - I see no activity in the server log what so ever. Facebook doesn't even contact the server. When using the alternate url - the one from the last edit, it pops up in the logs as it should.
EDIT
I filed a bug report with Facebook, And their first response was that they were going to follow up. Now, a month later, I got an email that said "We are prioritizing bugs based on impact to the developer community. As this bug report has not received much attention from other developers, we are closing it so as to better focus on the top issues", and then they told me to go here to stackoverflow to try to solve my issue - but the issue is WITH THEM, and of course no one else have reported that my site doesn't work, it affects only me, and I haven't opened it yet due to this bug!
EDIT
I wanted to file a new bug report, but I can't even that now, since they are blocking bug reports with this URL as well!
I had to edit the URL - here is the new bug report
When Facebook tries to scrap your site for information, they send a call to your server with specific user agent called "facebookexternalhit"...
Facebook needs to scrape your page to know how to display it around
the site.
Facebook scrapes your page every 24 hours to ensure the properties are
up to date. The page is also scraped when an admin for the Open Graph
page clicks the Like button and when the URL is entered into the
Facebook URL Linter. Facebook observes cache headers on your URLs -
it will look at "Expires" and "Cache-Control" in order of preference.
However, even if you specify a longer time, Facebook will scrape your
page every 24 hours.
The user agent of the scraper is: "facebookexternalhit/1.1(+http://www.facebook.com/externalhit_uatext.php)"
Make sure it is not blocked by your server firewall
Look in your server log if it even tried to access your site
If you think this is a firewall issue look at this link
Your problem appears to be with your character encoding string. Your Apache server is currently sending the unsupported string latin1. You've defined your meta:content-type as iso-8859-1. See the w3c validator
From what I've seen, the Facebook parser will stop immediately if it encounters either an unrecognized character encoding string or a mismatch in character encoding strings between your header and meta tags.
The problem could be originating from either your httpd.conf or php.ini files. Change these to match your meta and restart Apache. Since the problem seems to be domain-specific, I'd check httpd.conf first.
Could your domain be blacklisted? Could you try messaging your url to someone, and see if Facebook gives you a "This message contains blocked content..." error?
For example:
If you don't provide certain minimum Facebook markup on your page, it will respond with "Error Parsing URL: Error parsing input URL, no data was scraped." I only looked at the homepage, but it appears that dagbok.nu contains no Facebook markup. I'm not sure what things must be present at minimum, but in my implementation, I assume the fb:app_id meta tag and the JavaScript SDK script must be there. You may want to take a look at http://developers.facebook.com/docs/guides/web/#plugins , particularly the Authentication section.
I discovered your question because I had this same error today for an unknown reason. I found that it was caused because the content of my og:image meta tag used an incorrect URL to the image I was trying to use. So as you add Facebook markup to your page, make sure your values are correct or you may continue to receive this message.
This doesn't seem to be a Facebook problem if you take a look at what I've discovered.

Repeated tests loop these results when done a couple seconds apart indicating a page-redirect is occurring.
Security warnings are seen in Firefox and Chrome when visiting your site using these secure URL's:
https://dagbok.nu
https://www.dagbok.nu
The browser indicates the site should not be trusted because it's impersonating another site using invalid security certificate from *.loopiasecure.com
Recommendation: Check your .htaccess file, CMS Settings, page redirection, and security settings. Use the above source webpages to realize those file-locations / file-names that are being served to discover what's set incorrectly.
Once that's done, I think Facebook will be happy to then debug your webpage and provide additional recommendations.
Had the same problem and I discovered it was an incorrect IPv6 address in the AAAA records for my domain. The IPv4 record was correct, so the site worked in a browser but FB obviously check the IPv6 records!
This issue may also happen when Cloudflare is used. This is because Cloudflare protects the page from Facebook, which is then unable to collect the data, which in turn makes Facebook think the page is invalid.
My fix was:
Turn off Cloudflare for the page.
Scrape the page using Facebook's Dev Tools: https://developers.facebook.com/tools/debug/og/object
Click and let run the "Fetch new scrape information" button.
Re-enable cloudflare protection for the page.
You should then be able to continue to add the page where you needed.
I am running a URL through the Object Debugger, but it seems nothing is scraped for this URL. I get the following error message:
Could not retrieve data from URL.
Looking at the scraped data, only a single line has been scraped, which doesn't even correspond to the content in the the scraped page.
Edit:
This is caused by whitespace before the initial <html> tag. Removing any leading whitespace solves the problem.
Check if you use gzip in your page, disable it and try again. That fixed it for me.
Try this URL, Facebook tries to download but your server is not returning any data.
