Hi Gerard,
May I know which part of the sharing process is having an issue? Some screenshot of the issue would be great.
I tested this and it seems to be working(http://take.ms/hyFZk).
Also, can you provide us backend and ftp access to the site as we may need those to investigate the issue.

Hi Raymond,

the issue is that when we share with facebook, it works, we have a description and an image,
and when we share with linkedin, it doesn't we have only the url of the site

i can give you the access in a separate way

bests regards

Gerard

Hey Gerard,
I tried creating a similar post on my end and share it and LinkedIn seems to be able to crawl the correct image(http://take.ms/9juLs). Can you provide us your backend and ftp access at http://stackideas.com/dashboard/site so we can investigate this on your site? The credentials entered there will only be visible to Stackideas forum moderators.

Hello Raymond,

i just send the keys

regards

Gerard

Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Hm, something strange on your site, because it seems like something prevent Linkedin crawl your site, so Linkedin unable to retrieve your blog content when you trying to share.

May i know do you have setup anything from your server to restrict this?

I did checked from your robots.txt and trying to temporary updated all the directory file allow crawler to fetch content from your site based on following code, but Linkedin still unable to crawl your site.

User-agent: *

Disallow:

Even though I created a few test post on the site, it still unable to retrieve blog content, the reason why need to create test post to test this is because the first time LinkedIn's crawlers visit a webpage when asked to share content via a URL, the data it finds (Open Graph values or our own analysis) will be cached for a period of approximately 7 days.

This means that if you subsequently change the article's description, upload a new image, fix a typo in the title, etc., you will not see the change represented during any subsequent attempts to share the page until the cache has expired.

Hello,

it seems that with the addthis button,
there is a crawling by linkedin, but the image doesnt appear
it still works with facebook and not with linkedin
the directory image in not disallowed in the robots.txt
can you have a look on this issue ?

bests regards

Hey there,

I've added following code into your robots.txt file, it seems like Linkedin still unable to retrieve the image file from your site, but now it work for the Twitter share, you can check my attached screenshot below.

User-agent: Twitterbot

Allow: /images/

Currently that was difficult to check whether Linkedin server still cached with your existing blog content after I added above code when share in Linkedin, based on Linkedin API documentation, they did mentioned following statement :

The first time that LinkedIn's crawlers visit a webpage when asked to share content via a URL, the data it finds (Open Graph values or our own analysis) will be cached for a period of approximately 7 days.

This means that if you subsequently change the article's description, upload a new image, fix a typo in the title, etc., you will not see the change represented during any subsequent attempts to share the page until the cache has expired and the crawler is forced to revisit the page to retrieve fresh content.

Reference link : https://developer.linkedin.com/docs/share-on-linkedin

Facebook and Twitter social network already have their own debugger tool for allow user easier to purge the article content from their server in order to get the latest content when I share.
For example :
Facebook debugger tool
https://developers.facebook.com/tools/debug/

Twitter validator
https://cards-dev.twitter.com/validator
But unfortunately it seems like Linkedin still haven't build their own debugger tool, so we have to wait for another 7 days and see how it goes.

By the way, I did double check single blog page, those open graph meta tags already existing on the each blog post from your site, it should show correctly what Linkedin requirement that on their share API documentation page, you can check this link view-source:http://www.le-cercle-sirh.com/index.php/blog/nouveau-test (search for 'og:', check my third screenshot below)
