When sharing http://www.innovationservices.philips.com/ via an AddThis LI share button. Very old ... more than one year old ... images get loaded into the share popup. As I can see from googling this is LI cache, but that's not supposed to be older than ~7 days? Source: this forum and LI official replies.
Is there allready a solution to this. I'm willing to try adding a dummy parameter to my url, but this cahce is waaaay older than a week + I need the help of developpers for this + I'm not sure how this affects SEO (the meta tag solution)?
EDIT: I added google tags to the url, no effect (..?utm_source=wom_invite_mail&utm_medium=email&utm_campaign=WOM)
Is there a better way?
Tnx

Apparently LinkedIn is aware of this issue but haven't yet fixed it. See this question below.
How to clear Linkedin Share cache?

I developed a custom plugin for wordpress. In my plugin I´m using a linkedIn share button but when I try to share the article, linkedIn uses the wrong image. What have I done wrong? I tryed several solutions. og:image etc. are set correctly but I don´t know why it is not working.
Here is a link to the page:

Thank you in advance.
The cache may be out of date for the link you are trying to share. Use the Post Inspector to test sharing the link and to cache the latest changes.
I know this is an old topic but I've digged dozens of related questions and solutions but neither of them works.
Some of questions I've read:
Can't fix: 'og:image' property should be explicitly provided, even if a value can be inferred from other tags
Wordpress All In One SEO plugin not sharing to Facebook wall
My test url for facebook debug:

Also, I debuged via Facebook sharing debug and Facebook Object debug

here is the post's head tab:
I also add that sometimes this post could be displayed well (including image thumbnail) on my facebook page but most of time it did not.
I've cleared my wordpress caches.
Absolutely, I can read the social opengraph tab on my post but facebook failed to read them. I do not know the reason behind this problem. Please help me to be clear! thanks
EDIT:
This is a capture of the fact that sometimes Facebook receives my blog post well. And the post link is: https://trangthietbiytehcm.com/uncategorized/san-pham-test-lan-2/
And I wnat to add that the above test link (https://trangthietbiytehcm.com/uncategorized/bai-viet-mau/) also has the same fact as this
EDIT (UPDATE):
After months of be frustrated with this problem, I even tested on another new web on new host server. I've finally found that the reason of this problem is the page cache function of the W3 total cache
We've found this issue to be related to W3 Total Cache, too. Specifically, it's the Wordpress Dashboard > Performance > Minify > Eliminate render-blocking CSS by moving it to HTTP body feature. What this does is shove all the CSS right after the tag, moving all the other header tags down.
And it seems Facebook (and Twitter?) only parse a fixed amount of the page before deciding to try and render... and if your CSS is long, well, it never sees your og:image tag (or any others, like Title, etc).
We have yet to find a good fix which still allows this feature to be used.
I've got a site that has multiple share buttons on entries in a WordPress site.
We designed this so there are no individual entries to view, they're Podcasts and videos. The listing page has a minimum of 10 entries, each with share buttons.
Currently the share links and titles are working correctly. But the page is not recognizing the og:image, and instead is picking up the default logo for the site itself.
I read another post on Stack Overflow that said it might be an issue for LinkedIn if the image is utilizing SSL for the link. But I just find that hard to believe.
The other issue I'm struggling with, the docs say once an image is scraped it stays cached for approximately 7 days.
I had an issue with FaceBook and there's a debugger that allows you to rescrape the page which let's me verify my changes worked.
My two questions are, is there something other than the og:image i should be specifying? since I can't specify it per post, it's in the head of the page itself, i would think it would pick that up. No?
Second, is there a way a developer can re-check after the meta info has been changed to see if the changes worked, without having to wait the TTL on the cache?
try this:
url/link?blah=1
url/link?blah=2
url/link?blah=3
to get around the cache.
This should trick it into thinking its a new page each time.
Can i get a link to test?
Anthony Walz posted the correct answer. Through email he also helped another problem i had which corrected a new issue i didn't realize I had until i looked.
my LinkedIn shares were not picking up the show title, they were picking up the page description instead (i have several podcasts showing on one page, we don't use individual post pages, they all play from the listing.)
he pointed me to the developer docs on formatting sharing links
Which gives a real world example - here:
https://www.linkedin.com/shareArticle?mini=true&url=http://developer.linkedin.com&title=LinkedIn%20Developer%20Network
&summary=My%20favorite%20developer%20program&source=LinkedIn
Thanks a ton for assist Anthony!
Im having issues with my project right now regarding linkedin share. The image(thumbnail) doesnt showed up.
My question is, does the url change could also affect?
For example i added the og tags like this:
https://domain_name.com/wp-content/uploads/2016/10/2_About-Team-Photo_New-1.jpg
but when i open up the source code the url was change to:
https://d2gkdq5vdbd74s.cloudfront.net/wp-content/uploads/2016/10/2_About-Team-Photo_New-1.jpg
Does this change affect the Linkedin Share?
By the way the facebook share has no issues at all.
Please help me. Thank you.
Reggards,

My hunch is that your page doesn't have the Open Graph prefix on its or tag.
<html lang="en-US" prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# website: http://ogp.me/ns/website#">
I believe I've come across that as an issue with LinkedIn shares in the past. As for the URL change, that shouldn't impact it. I believe I've used images from different domains successfully in the past for Open Graph. Do you have a plugin enabled that might be syncing your assets to CloudFront or S3? That might be the cause of that.
I wrote a plugin a while back that might save you some hassle with all of this -- it comprehensively and intelligently adds all of OG tags needed, including the prefix, and allows you to customize that data as you need per page or globally (if you're a developer, you can do this all programmatically with some built-in filters. It also lacks the confusing configuration and bloat of other 'do it all' plugins, which is one of the main reasons I built it. You should check out:
https://wordpress.org/plugins/complete-open-graph/
My problem is that I was using a "Like button" plugin on wordpress and I didn't liked the looks of it. I deactivated the plugin and then tried with manual code of XFBML button. That screwed the count to some of the posts, having their counts all in one. I reverted the changes, using the plugin again, deleted the code added and the problem persists. Some of the posts have the "shared" count box. And when you "Like!" any of that posts, only the last one appears on Facebook.
It's it possible that this is a caché issue or something that is wrong in the code?
I tried reverting the meta tag "og:type" from "blog" to "website" but it didn't allowed me, can this be the problem?
Why do some of the posts share that countbox if the links are not the same?
And the wierdest thing, why only some of the posts have the issue while some are shared correctly?
As for an example, say post 1, 5 and 7 share the same countbox (+200). When you "like!" any of them, only the last of them (the most recent) gets to the FB wall.
This doesn't happen with the new posts, only with part of the old ones.
If the case, you can see it working: http://elrincondelacritica.com/
Thanks in advance.
By the way, if you need any piece of code just ask, this is not my page and I really need to fix this asap, also because it's online and running.
Thank you.
The FB debug tool shows that you didn't supply the fb:app_id > which seems to be crucial to render the news feed.
See: https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Felrincondelacritica.com%2F
You can create a Facebook App here: http://developers.facebook.com/apps
Once you've done that you can add the fb:app_id by adding this into your header:
<meta property="fb:app_id" content="000yourAPID000"/>
Thanks mate for the share. Next time I make a website I'll make sure to create an APP too.
And by the way, the error was because of the meta tag og:type changed from website to article. What I did was to leave it to article (not trying to change it "forcing" og:type - website) and placing each "bad" post in the FB Debugger. There were 30 or so... but it worked, and now the new posts work too, with zero count from the start and incrementing correctly, each in particular.
