Hi Adam,
Sorry about that.
So it appears that your widget is not able to find the following files:
http://trenchcity.com/wp-content/plugins/tubepress_pro_3_0_0/src/main/web/players/shadowbox/lib/shadowbox.js
http://trenchcity.com/wp-content/plugins/tubepress_pro_3_0_0/src/main/web/players/shadowbox/lib/shadowbox.css
The reason is that it is missing a '/' in the source.
They should look like this:
http://trenchcity.com/wp-content/plugins/tubepress_pro_3_0_0//src/main/web/players/shadowbox/lib/shadowbox.js
http://trenchcity.com/wp-content/plugins/tubepress_pro_3_0_0//src/main/web/players/shadowbox/lib/shadowbox.css
Please try replacing these links within your header, and the widget should start working properly.
Please let us know.
Thanks!
