Hello, we’re sorry to hear that you’re facing an issue with the preview image not showing when sharing to LinkedIn. Since you’ve already checked that the OG image tag is present, the image is accessible, and the size and weight are correct, here are a few additional steps you can take to troubleshoot this issue:
1. Check for Minification Issues
If you’re using a caching plugin that minifies your CSS or HTML, it might be pushing your Open Graph tags too far down in the source code. LinkedIn and other social networks typically only look for Open Graph tags in the first 60 KB of your page’s source code. If they don’t find them there, they may assume they are not present.
2. Gzip Compression
If you have gzip compression enabled in your caching plugin, it may interfere with LinkedIn’s ability to read your Open Graph tags. Try disabling gzip compression and then clear your website and server cache.

3. Validate with LinkedIn Debugger
After making these changes, use the LinkedIn Post Inspector to scrape your URL again. This tool can help refresh LinkedIn’s cache for your URL and may resolve the issue.
4. Check for Conflicts
Ensure that there are no conflicts with other plugins or your theme that might be affecting how the Open Graph tags are rendered. You can follow our troubleshooting guide for more information on identifying conflicts.
If you’ve tried all these steps and the issue persists, please reply to this ticket with your site URL so we can assist you further. Thank you for raising this concern, and we hope to help you resolve it soon!

Bonsoir, j’ai déjà vérifié tous ces points, pas de minification ni de gzip en place, et la validation LinkedIn m’indique que je n’ai pas de og image renseignée alors qu’elle l’est. Pas de conflits non plus.
Sur la page d’accueil du site en revanche, le og image est bien détecté, avec une image elle aussi en webp.
