While trying to click into a WP post from LinkedIn, I noticed my permalinks aren’t working. This is a recent issue that seems to have popped up without any changes on my part, except regular version updates. Any clue why the sudden problem? Any clue how to fix?
Here’s the error message I get:
Fatal error: Call to undefined function has_post_thumbnail() in /UnixWeb/home/l/myusername/www/blog/wp-content/plugins/wp-facebook-like-this/wp-fblikethis.php on line 252
