Hi - I have been using the "video thumbnails" plugin with "Automatic Youtube Video Posts Plugin" successfully for a couple of weeks on my site.
I had used this fix to make them work together:
changed the line
$markup = get_post_meta( $post_id, $video_key, true );
$markup = 'http://youtube.com/watch?v=' . get_post_meta( $post_id, $video_key, true );
and set the custom field value to _tern_wp_youtube_video.
Now i just went to the "video thumbnails" plugin settings page and the page is blank so i added a / to the end of the page url to make it display the page.
The Save Changes button still works but when i click the "scan past posts" nothing happens!
I have tried uninstalling the plugin and reinstalling but its no good.
Please help - thanks
