Broken examples

Hello,

I try the `player_basic.html` example and it looks broken (inactive player and all button are inactives). I'm on Ubuntu / Firefox 78.0.1.
In the web console, there's an error :

Uncaught (in promise) TypeError: e[t] is undefined
i https://cdns-files.dzcdn.net/js/min/dz-v00401202.js:2
n https://cdns-files.dzcdn.net/cache/js/legacy.d4bebcd0f24198004bf4.js:2
s https://cdns-files.dzcdn.net/cache/js/legacy.d4bebcd0f24198004bf4.js:2

The same error appear on the [Deezer Javascript SDK examples on the official documentation](https://developers.deezer.com/sdk/javascript/example-basic)
