I have a website that triggers a warning when clicked through a link shared on facebook. The warning says: \"Possible problem with this link We have detected that this link
Following the already mentioned link to the Facebook object debugger, make sure that your og tags are written RIGHT AFTER the opening <head>
tag.
Not sure why this happens but I used to run into the exact same issue until I moved them right after it and then clicked once again on "Fetch new scrape information
".
Hope this helps!
