OK, I was implementing the fix you gave and it went fine with the first file, bu twiht the 2nd file, my file "gavern/helpers/helpers.layout.php" does not have the text string:
"$image = wp_get_attachment_url(get_post_meta($postID, 'gavern_opengraph_image', true));" at line 224.
It has
"$image = get_post_meta($postID, 'gavern_opengraph_image', true);" at line 224. Do I add the new text string anyway?
