I've been running a blog for years now, and sharing blog posts (with the correct thumbnail, title and description) on Facebook always worked fine. Last week however, when sharing new blog posts, all the meta data was obviously missing - Facebook didn't even pick up the title of the page. When debugging the new blog posts, I get:
Response Code : 503
Missing Required Property: The og:url property is required, but not present.
Missing Required Property: The og:type property is required, but not present.
Missing Required Property: The og:title property is required, but not present.

When debugging old posts (and by old I mean posts published before that day when Facebook suddenly decided to stop reading meta data from my site), everything's there, I can share the link with picture, thumbnail and description.
There are two things troubling me:
1) I have all important meta tags explicitly specified in my header and my functions.php - when viewing the source code for the blog posts (see for yourself here: http://www.discodemons.net/2012/02/16/moullinex-peaches-maniac/
) , everything's there. I didn't change anything on my blog for weeks (or maybe months), and yet, from one day to another, I can't share my links on Facebook correctly anymore - even though all the required meta data is there.
2) Facebook is able to pull title, image etc. from even the most simple sites, that don't have any meta data included. I've tried and removed all the meta data from the header and functions.php, and yet facebook couldn't pull any information from my site?!
I've tried disabling all comments, tested some WP plugins that put the correct meta data in your source code, disabled them again, even removed all FB-related plugins such as like/sharing button etc. Any help on this much appreciated, I haven't got a clue how I could possibly fix this!
It seems as though your WP server is returning a 503 server error for all scrapes from Facebook. It may be that this is a security feature you enabled recently, or a plugin that attempts to serve different content to Facebook for the purposes of scraping.

This worked just fine a few days ago. Now, FaceBook refuses to fetch the image when I paste the link in the website (title & desc ARE fetched). It worked just fine when sharing via Google Plus (all info fetched).
I'm trying to share a link from my website via my website's FaceBook page.

I've always had some warnings in FaceBook's sharing debugger so I don't know if this is some breaking change they added. One of the warnings now is "Share App ID Missing". You can see their report here:
https://developers.facebook.com/tools/debug/sharing/?q=http%3A%2F%2Fmentatul.com%2F2016%2F08%2F17%2Fis-yoga-really-an-entry-drug-to-buddhism
I have no App ID yet. I set one up but I don't know how to link to the website. I googled and found a StackOverflow post related to this but the information there is outdated. I did add the fb:app_id value to my metas but to no avail. The warning is still there...
I've no idea why it's warning me that "The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.". There is only one mention of that tag on that page and it's quite explicit!
Facebook LIKE/SHARE functions are generally not working on my wordpress blog. I cannot LIKE or SHARE any new posts, but oddly if I have already LIKED a page, the SHARE function works fine.
The problem with SHARE is that the normal sharing window pops up, but there is no metadata populated in it. I've looked at the metadata in my blog posts and as best I can tell it is populated correctly by Wordpress. Additionally, I cannot find any differences in the metadata or code between posts that I have previously LIKED and ones that I have have not.
I've tried running the FB debugger/linter for a number of posts on my site and each one returns the message:
Error Linting URL: An internal error occurred while linting the URL.
I've tried googling this error, but cannot find any useful advice on what might be causing it.
Here is a sample post for people to examine this problem:

Thanks...
You should use Open Graph tags (see "Use proper Open Graph tags and large images to generate great previews" and "Using Self-Hosted Objects") in the header of your webpages to help Facebook determine what metadata needs to be shared.
Since you are using WordPress, you could either edit the template file in your theme that defines page headers (normally header.php) or use Facebook's official plugin.
The Documentation from facebook isn't understandable, atleast for me.
I have never worked before with facebook and had a basic requirement of putting a like button on Product pages.
So yesterday, I added the OpenGraph meta tags and like button to my Product pages as stated in this documentation, https://developers.facebook.com/docs/opengraph/. I also created an app, as the document stated that it has extended the basic meta data to add a required field to connect your webpage with Facebook: fb:app_id.
The like button has been set but i have few queries which are as following :-
For some pages, the like button doesn't read the og tags. Rather than publishing the whole thing in a story manner by reading og tags, it just shows a link. During googling, I read it happens because of facebook caching and since, I shared the link on facebook before putting the meta-tags, this is happening. So, Is there any way that I can direct facebook to reset all the caching for my pages or scraping that it has done earlier.
Though I have created the App, I actually have no idea what to do with it. Why is it needed and what matters it can help me with.
I tested one of my URLs here: Facebook Linter but it shows some error and stuff which i can't understand. Below is the image. Please tell if I have done anything wrong and why it's showing these errors
Documentation for OpenGraph on Facebook containing outdated information about pre-defined types, see OpenGraph Types. You probably need to define your custom Object Type "Product" in for your Application/Site using Developer Application in Open Graph settings.
You may want to read Documentation for OpenGraph beta too.
Update:
There is a similar question about exactly this og:type: Opengraph meta tag og:type set to “product” errors (like button & URL linter/debug)
I'm currently using Drupal 6 with a special content type template for all blog posts. At the moment we're not using OG tags but I have it pull the main metadata with content-type, title, image, and description tags and it was working just fine until today.
Despite at least the last 3 posts still displaying properly in URL Linter, the newest for today won't pull any of the metadata. A few other ones I tested at random from the archive aren't pulling information properly either, but the majority are still working.
What would cause a discrepancy in Facebook's URL Linter between pages using the same template?
What is the url? Are the tags in the header? Are you able to test switching to their new OG open graph tags? Facebook has been known to deprecate old functionality with little to no warning - and perhaps the old url's are working still because Facebook has already cached the data. It looks like a lot of people are having this same issue - and I am assuming Facebook will fix it soon if it isn't already fixed.
When we first put up a blog post, Facebook often (but not always) gets confused about what the page is. Specifically, if you try to use the Like button on the blog page OR if you try to share via the Share link on your profile, Facebook will see the root blog page rather than the actual post page.
For example, we recently posted:
http://thisorthat.com/blog/2010-song-of-the-year-round-1-results
If the user "likes" it, it returns the title for:
"http://thisorthat.com/blog"
When you run the post URL through the FB Linter, you can see the problem.
"http://developers.facebook.com/tools/linter?url=http://thisorthat.com/blog/2010-song-of-the-year-round-1-results"
In the Debug section it shows an extra og:title, og:url, description and og:image (the last 4 rows of the Debug section). This is the meta data from the root directory. What we cannot figure out is why. Why is Facebook seeing the correct meta data on the page and then also pulling the meta data from the root directory (and using that incorrectly to populate the data for the Like button and the Share URL tool)?
One other oddity. FB "figures it out" after a few days. Of course, by that time relatively few people are viewing the post.
UPDATE -- I want to thank Peter Bailey again for his answer, but we also discovered that there was another issue that we had to resolve before the Like button worked.
The issue was that we were displaying the Facebook the Like button on a post that was not yet published. The problem with this is that FB then can't resolve the URL and "guesses" as to the correct URL. In our case, it always guesses thisorthat.com/blog. Unfortunately, it then caches that guess for a number of days and that cache cannot be cleared by the Linter. So the ultimate solution was to both fix the og:type as Peter suggested, but also to remove the Like button from the blog post preview. It's very important that you don't show FB a page before it's published or if you do, change the URL.
Pretty sure it's your Open Graph type that's the problem.
<meta content="website" property="og:type"/>
Per the documentation
Use article for any URL that
represents transient content - such as
a news article, blog post, photo,
video, etc. Do not use website for
this purpose. website and blog are
designed to represent an entire site,
an og:type tag with types website or
blog should usually only appear on the
root of a domain.
