Page metadata isn’t the sort of thing that should change very often, but you can manually clear the cache by going to Facebook’s Debug Tool and entering the URL you want to scrape There’s also an API for doing this, which works for any OG object: curl -X POST \ -F “id={object-url OR object-id}” \ … Read more
This is a bug, and it’s confirmed, after getting the warning, if you retry the debug, or click on “Scrape Again”, the error message will be gone. This is an issue because if someone tries to share the post, the image will not show up since it didn’t get scrapped, but subsequent shares will display … Read more

First, I want to reiterate that I am almost positive that your problem is due to the fact that the url you are passing into the debugger is not dynamically generated. The url tag essentially acts as a redirector. Unless it’s the exact same (meaning the meta tags on the url meta object is the … Read more
This answer I found on LinkedIn forums might be of help to you: Guys, I’ve spent a whole day trying different things. What worked for me is using the mata [sic] tags as following: <meta prefix=”og: http://ogp.me/ns#” property=”og:title” content=”{Your content}” /> <meta prefix=”og: http://ogp.me/ns#” property=”og:type” content=”{Your content}” /> <meta prefix=”og: http://ogp.me/ns#” property=”og:image” content=”{Your content}” /> … Read more

So in your code, you don’t have to remove the FB.init function, just make sure you don’t pass parameters in the code that loads asynchronously the JS SDK. Replace this: js.src … Read more
Today I had a much clearer answer to this question (from the Open Graph debugger tool): Small og:image: All the images referenced by og:image should be at least 200px in both dimensions, with 1500×1500 preferred. (Maximum image size is 5MB.) Please check all the images with tag og:image in the given url and ensure that … Read more
If my code access the Pages API and shows the result on my website, is it “used by [a] reduced number of people”? You are most likely the only consumer of the API in your application. Since it’s an AJAX call in the background and not a login based application, the “reduced number” situation should … Read more
For HTML5, add this to your html element like described on ogp.me and keep your og: prefixed properties: <!doctype html> <html prefix=”og: http://ogp.me/ns#”> <head> <meta property=”og:type” content=”website” /> … For XHTML (like OP’s question), use the name attribute instead of property attribute. Facebook lint will throw a warning, but the meta value will still be … Read more
