I was running TubePress Free. I upgraded to TubePress Pro and also installed the Black Bar Remover and Flexible Thumb Nail Rows add-ons.
All is working well except the thumbnail rows are not adjusting in height as expected. The setting for this add-on is displayed at the bottom of the thumbnail settings page; therefore, I assume the plugin is installed correctly. You can see this in action on this page: http://automotiveedu...youtube-videos/
Thanks in advance for help on this matter.
