Blogs not displaying properly
I've added the “Recent Blog Posts” widgets into the “Main Sidebar” and I get the following error displayed
Fatal error: Call to undefined function has_post_thumbnail() in /home/burtona1/public_html/wp
-content/themes/classipress/includes/sidebar-blog-posts.php on line 47
Also I can't see the “Post Thumbnail” module box in the blog post edit window.
