Sorry, I am unable to validate this document because on line 570 it contained one or more bytes that I cannot interpret as utf-8 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.
The error was: utf8 "\xE1" does not map to Unicode
Your page does not even have "og:description", it usually just works fine if you put in the correct metatag. I know that the YOAST SEO plugin (the one you are using) does allow you to set up a description for every article, just below the article text in the edit window there is an input field called "Meta Description".
