Ok I recently installed SEO by Yoast on http://www.waltermonteiro.com ...I use this plugin for other sites as well.
However, on this one, when I write a blog, and paste the link on Facebook, the description comes up as "You may use theseHTMLtags and attributes:<a href="" title=""> <abbr title=""> <acronym title=""> <b> <blockquote cite=""> <cite> <code> <del datetime=""> <em> <i> <q cite=""> <strike> <strong>" instead of description. It ONLY does this to the most recent post. All older posts work and display correctly it is always just the most recent that appears wrong, and the most recent blog is usually the most important. Using TwentyTen theme...any help would be great!!
