UI stops working after installation of volspotconnect

I have installed the volspot connect on a 2.31 version and the UI not working anymore.
I made a fresh installation it seems I am able to reproduce the issue every time.
Here’s what I did.
Fresh install volumio 2.31 in the setup wizard I set up the sound interface to hifiberry dac, added samba share in this point everything works well. Reboot.
In the plugin manager I am going to install the current version of https://github.com/balbuze/volumio-plugins/tree/master/plugins/music_service/volspotconnect the installation succeeded. Reboot the device.
The web UI does not respond anymore, but ssh works well.

oups, sorry but I think there is a small problem in a file. I try to correct it until tonight.

edit : done in new version but can’t check deeply now…

Wow thank you for your lightning speed response, now it it working well thanks.
