Spotty doesn't appear in my plugins

Hi everybody,
First thanks to Mickael for his work on spotty.
I use LMS on a NUC with debian 8 and squeezeboxes radio, I'm also using ipeng and orange squeeze.
Concerning Spotty, everything works well with ipeng and orange squeeze but it doesn't appear in LMS menu web page.... (my apps) ... I tried to reinstall but nothing. I have the same issue with TuneIn
Do you have an idea to make it appear ?
It's LMS 7.9.0.

Thanks in advance for your help
