Seems simple enough, but I can't wrap my head around it. I've searched around online but I couldn't find any solution to it.
When I copy and paste the url for my blog's homepage, http://www.radiocontrolplan.com/ , onto Facebook, the preview (the title, thumbnail and text snippet) is not of my homepage and my website's description, but of one of my old blogposts - randomly.
If this helps, I'm running the All-in-one SEO plugin. I did not notice whether this started after running this plugin or not.
