Here's a problem: I've got some number of links posted to groups "as is". That posts look like a link, nothing more. Is there a way to make that links crawled to previews, as Facebook automatically does when we share a link or post it with a minor delay? Without re-posting them.
I've had that with slow internet connections or weak devices.
Or you can read this: http://www.robblatt.com/technology/facebook-previews-not-working-heres-a-fix/
Anyhow, if it doesn't show the preview at any try, you should - before trying again - refresh the page, as (mentioned in above link) if it doesn't go the first time, it never will, unless you refresh.
otherwise, did you update the page recently (or was it recently updated)?
Edit: try adding this to the end of the link: ?=1

The images of links shared from my website disappeared from my FaceBook business page.
I have a WordPress blog.
For about a year, there was no problem: if I shared a link from my website on FaceBook, the featured image was displayed.
A month ago, two problems arose:
Most of the images of links shared from my website disappeared from
one moment to another.
If I shared a new link from my website, the
image was displayed, but as soon as I posted something again, the
image belonging to the previous post disappeared.
I asked help from a developer (I am not skilled in programming), who fixed the problem for the future, so hopefully links I share in the future won't be affected by this problem. However: I still have 50 older posts the featured image of which are not diplayed.
This is my FaceBook Page: https://www.facebook.com/izekmentesen/ Please scroll down to see there is no image displayed for older posts.
This is a recipe blog, so older posts are just as important as new ones, they will not loose their relevance.
Could anyone help me fix this issue?
I already tried these:
I tried to deactivate all plugins one by one. After each deactivation, I refreshed the cache of my website, re-fetched one of the affected links with FaceBook Object Debugger and checked if the image was diplayed on my FaceBook page. Nothing happened.
I tried to change the image (then refreshed the cache of my website, and re-fetched the link of the post with Object Debugger). This did not solve the problem either.
I set my Open Graph plugin to use the first image in the post as an og:image. (By default, it would use the featured image.) No success.
Whenever I make Object Debugger fetch a link from my website, I got this warning:
Extraneous Property: Objects of this type do not allow properties named 'og:site_name'.
The same warning is given concerning to: 'og:title', 'og:url', 'og:type',
'og:description','og:image','og:image:url', 'og:image:secure_url','og:image:width', 'og:image:height', 'article:publisher' and 'fb:app_id'.
I would really appreciate if someone could help me.
I have started to experience a really strange problem with Facebook link scraping/caching which seems random in nature.
On brand new posts when I go to check: https://developers.facebook.com/tools/debug/ with my new URL I get a message saying 'Cannot scrape: URL blocked'
We have literally been sharing URL's to Facebook for YEARS with no problem whatsoever. All open graph tags are present and working fine.
What is really weird is if I just manually press the 'scrape again' button it grabs all the bits properly and says everything is fine. It's always just the first attempt.
I have also tried manually calling the scrap API instead of letting Facebook do it when someone shares the URL for the first time and still sometimes (not always) it returns empty (just 'id' and 'url' returned) indicating the URL was blocked.
What's going on here it's driving me mad? We are nowhere near our API limits if maybe that was the issue...
Why would it say blocked first go on the debug page then literally 2 seconds later you press 'scrape again' and it works fine.
Just to note sometimes when it says blocked it still shows maybe the image in the link preview but no title or description. It's like it's grabbed some tags but then given up. Very strange...
I have checked our access logs and I can see 'Facebot' accessing our site fine.
Hope someone can help, I am really hoping this is some weird Facebook bug as I can't see any change in our code base that would effect this.
Facebook does not return anything helpful when this happens even with the API. I have no way in contacting Facebook direct either. If we are somehow getting blocked I would love to know why and fix that issue. But it's impossible to debug at the moment.
Just to note I have 3 sites all running the same code base (WordPress environment). They are all experiencing this issue. All been running fine for many years.
Cheers
This was to do with rate limiting that was not visible in the Facebook APP dashboard. Helpful...

Solution for your problem: You can use Facebook image button after adding link on Facebook news feed, like shown in iamge
second thing upload image on othe site and give the image path to your website and then put it on your news feed, you can get definitely positive result using this two methods.

thanks hope this two will work for your problem
I have a site www.line4ever.com, first time I wrote url in facebook it shows a featured demo article of the template. I erased it from the site, and wrote an article with the information. But facebook keeps showing the now non existent featured article.
I thought it was a cache, but three days later I still have the problem. Any ideas? Thanks.
Try taking a look using the facebook debugger tool.
https://developers.facebook.com/tools/debug/og/object?q=www.line4ever.com
You can see what errors there might be and what the cached version of the page looks like. Although 3 days does seem like a long time for a cache, there's probably more factors Facebook take into account (popularity etc.) before they invalidate a cache
I created a Facebook OpenGraph App which was integrated with my website http://liveofofo.com everything worked fine but the problem is that not every read action triggers a post to timeline, as a matter of fact, it may not work in days meanwhile, I have the same Opengraph plugin and settings on another site (ghanamovie.org) and it works perfectly, all read actions triggers a post to timeline
I have done a lot of troubleshooting but I still can't get what exactly the problem is, I'll appreciate any help suggestion.
I took a quick look at the source code for the first article on the page.
The Open Graph meta tags are repeated several times on the page (and are not in the <head> section of the file).
Take a good look at the structure of your code and use the Debugger to see if Facebook approves of your syntax.
If there is a problem when you are posting the Open Graph action, log the error message. It will probably tell you why the post failed.
I'm currently having trouble using facebook like button in html5 version, it seems that everytime the visitor of my wordpress blog liked a blog post, it's not working. It will work for a while but when you refresh it, it goes back to active button which is very strange since the user already liked the blog post.
I also encountered that when i liked my own blog post, it fetched the wrong details. example, i liked the blog post #1 but when i check my facebook, it the fetched image is wrong, the description and title is also wrong.
what is the proper way to add a facebook like button in wordpress blog?
any help?
I also encountered the same error before. I already tried the linter to debug it but it really doesn't work. Anyway, my simple solution to that is I changed my facebook like code to Iframe version (since html5 give me crap, there's no harm if I use iframe lol). I don't encountered any errors with that. It works perfectly.
about your question on how to add facebook like in your index file or multiple blog posts in wordpress, the link (guide on how to...) might help you. I used that before. It also discusses about twitter tweet, google plus and pinterest pin it button's wordpress implementation.
have a good day!
