Jukebox does nothing

Hi all I'm trying to add some sound effects to my dungeon but nothing is happening. I can click on one of the four tabs, type in a search in the "Search for" dialogue box (like 'dungeon' for example), but that's it. When I hit Enter, nothing happens. Nothing at all. No busy icon spinning - absolutely nothing at all happens.   What am I doing wrong?

Can you post a screenshot please?

That's it. It doesn't matter if I scroll down, hit enter, or anything. 

Have you tried in both Firefox and Chrome?

Just tried it and the exact same thing happens. I do a search, I press Enter, and all it does nothing at all. 

Does it happen on the BattleBards and the Incompetech tabs too? When you click the tabs, before you search you should see tracks listed. EDIT: Also, try disabling all browser extensions and add-ons.

I do see the listings but as soon as I type in anything (like dungeon or rainfall), it all disappears. EDIT: Ah...I see how it works now. It works a little differently to how usual search engines operate.  Thank you for your help.
