Every time I try to share my default url (the homepage of my website) on facebook, it shares the image (and meta description) of my last post. I want to be able to share the main url with a specific picture and description of the website , but it doesn’t allow me to do so. It’s very confusing and misleading when I share the mail url and it shares the image from my last post.
I’ve tried to install plugins that are supposed to do that (like Thumbnail Fixer for Facebook) but I can’t seem to able to override the theme main settings regarding that.
