I have the same problem. Up to now I could write whatever I wanted in description and it would show when sharing the posting on Facebook. Now when I share a posting on Facebook I get whatever I wrote in excerpt. What is the problem? Thank you!
@lolaheavey I received some assistance here – http://wordpress.org/support/topic/plugin-all-in-one-seo-pack-keywords-not-appearing?replies=11#post-2972640 from Peter. I’m not sure if it’s going to fix my problem with the snippets, I just implemented the changes the other day but it may be worth a look. I had a terrible experience and I’m hoping to recover, my post pages were dropping out of search, where my post was once appearing in the first 10 now they were either non existent or I was appearing on page 50 of search results. This has been going on since the update. Hope the above helps.
