I was going nuts trying to figure out why the LinkedIn share button on my site wasn't working correctly. When you shared, the LinkedIn share window that came up pointed back to the blog homepage with no image and no title versus having all the right info (the title of post, URL and image).
It was almost as if LinkedIn wasn't seeing the Open Graph tags. Well, it turns out that it wasn't seeing them. Past posts worked fine, but I noticed new posts since I installed this plugin had the sharing problem. After some troubleshooting, I realized that if I turned off the "Enable Default Banned List" feature under "Ban" then sharing worked perfectly.
There must be something on that banned list that blocks LinkedIn's bot. Obviously, this isn't something people want to block, as it makes sharing a major problem for LinkedIn. I tried to look through the list and see if there was something obvious, but I couldn't find something. Any ideas what blocked bot on the list is causing LinkedIn's bot to also be blocked?
