I cannot get my Facebook thumbnails working properly. For older posts (back when I didn't have this issue) I have those thumbs available to choose from. But for new posts, nothing. Plus, some of the available thumbs are my social media buttons, which I don't want to ever use (or have available to use) when I post a link to my Facebook page.
Please help. I'm pulling my hair out. For days, I've been working on researching and fixing the issue. I'm not having any luck and I see that many people have posted about it. I've tried so many methods but I haven't been able to fix it.
Would someone mind looking into my site? Actually, it seems to be all the sites that I use a TwentyEleven child theme. But here's one to look at that has this problem with Facebook thumbnails. There does appear to be the add_theme_support( 'post-thumbnails' ); in my functions.php document, but I'm not terribly familiar with php, so a lot of it doesn't make clear sense to me.
Thanks for the help in advance!
