Hi,
Sure, this happens when:
1. Either Open Graph Meta Tags are not present in the HTML source of your website
To fix it, you can install our Open Graph Meta Tags plugin https://wordpress.org/plugins/heateor-open-graph-meta-tags
OR
2. These are present but Open Graph Meta Tags cache needs to be cleared at Facebook’s end.
To fix it, you need to enter the problematic webpage url (where you are facing issue with sharer not grabbing proper meta tags content) at following link:
https://developers.facebook.com/tools/debug/og/object/
and click Fetch new scrape information
button. Now, you should be able to see proper content in sharing window at that webpage.
You need to do this for all the webpages where you are facing this issue.
P.S.: Our plugin mentioned above, clears Open Graph Meta Tags automatically, whenever you update/publish a post/page.
Thank you for your fast and very helpful reply 🙂
Awesome!!!!!
