Hello, all! I was having the same problem with the free adapt theme, and I found that changing a couple of lines in the “Slides.php” file fixed it:
// $slidelink = get_post_meta($post->ID, 'adapt_slides_url', TRUE);
$slidelink = get_post_meta($post->ID, 'wpe_knowledge_slides_url', TRUE);
// $slide_description = get_post_meta($post->ID, 'adapt_slides_description', TRUE);
$slide_description = get_post_meta($post->ID, 'wpe_knowledge_slides_description', TRUE);
I included the original (commented out) code, and the slightly tweaked code. Seems the variable was being fed the wrong values.
I found the right values by studying the html source of the slide posting page.
Anyhow, it worked for me, your mileage may vary…
